Preface
3.14159265358… has been used as a value for the last 2000 years. This
number actually represents polygon of Exhaustion Method of Archimedes (240 BC)
of Syracuse, Greece. This is the only one geometrical method available even now.
The concept of limitation principle is applied and thus this number is attributed to
the circle. In other words, 3.14159265358… of polygon is a borrowed number and
attributed/ thrust on circle as its value, as the other ways, to find the length of the
circumference of circle, has become impossible with the known concepts, principles,
statements, theorems, etc.
From 1660 onwards, 3.14159265358… has been derived by infinite series
also, starting with John Wallis of UK and James Gregory of Scotland. This number
was obtained by Madavan of Kerala, India, adopting the same concept of infinite
series even earlier i.e. 1450. The World of Mathematics has recognized very
recently, that Madavan is the first to invent infinite series for the derivation of
3.14159265358. John Wallis and James Gregory too invented the infinite series
independently though later in period (George Gheverghese Joseph of Manchester
University, UK).
C.L.F. Lindemann (1882), Von K. Weirstrass and David Hilbert have
called 3.14159265358… as a transcendental number. The basis for their proof was
Euler’s formula ei
+ 1 = 0 (Leonhard Euler, Swiss Mathematician, 1707-1783).
With their proofs, squaring of circle has become, without any doubt, an
unsolved geometrical problem. Thus, the present thinking on is, 3.14159265358…
is the value which is an approximation and squaring of circle is impossible with the
number.
At this juncture, the true and an exact value equal to 14 2
4 =
3.14644660942…. was discovered by the grace of God in March, 1998 after a
struggle of 26 years (from 1972) adopting Gayatri method. Hence, this value is
called the Gayatri value as the Gayatri method has revealed the true value for the
first time to the World. It was only a suspected value then, and however, it was
ii
not discarded, by this author. He continued and confirmed 14 2
4 as the real
value with Siva method, Jesus method and later with many more methods only.
A dilemma has thus crept into the minds of the people, which number
3.14159265358… or 14 2
4 = 3.14644660942 is the real value. One
responsibility before this author was to clear this dilemma. And, therefore, a book
was written collecting the work done in the past 12 years and titled Pi of the Circle in
2010, and is available in the website www.rsjreddy.webnode.com
The second responsibility before this author was also, to search for any flaw
in the derivation of the present value of equal to 3.14159265358…
As a result of continuous search for 16 years further deep, two errors have
been identified. And one paper has been published. One is, that, 3.14159265358…
belongs to the polygon and not to the circle. The second error is, to call of the circle
as a transcendental number. They (Lindemann, Weirstrass and Hilbert) may be
right in calling 3.14159265358… and not . Why ? It has been shown in earlier
paragraph that Euler’s formula is the basis in calling 3.14159265358… as a
transcendental number. In the formula ei
+ 1 = 0, refers to radians equal to 1800
and not constant 3.14…. constant has no place for it in the above formula.
When 3.14… is involved in the Euler’s formula, the formula becomes wrong. Is it
acceptable then to call constant as transcendental number even though this has no
right of its participation in the above formula ? However, it is acceptable still, if one
agrees that radians 1800 = constant 3.14 or radians 180
0 is identical to
constant 3.14… Mathematics may not accept this howler.
Thus, on two counts i.e., 3.14159265358… is a polygon number and calling it
as a transcendental number, based on radians 1800. The present work on
unfortunately, is confusing. These are the two simple errors to be rectified
immediately. Here, the NATURE has kindly entered and rectified the errors by
revealing Gayatri value. It is exact and is an algebraic number. Squaring of circle
is also done, by IT’s grace.
iii
In this book there are two unpublished papers also, one is to show the first
method the base of this work after 26 years of struggle (Gayatri method) and two is
is, not a transcendental number (Arthanaareeswara method).
Fifteen papers on value have been published by the following international
journals. The World and this humble author are grateful, forever, to these Journals.

How did this Zoology Lecturer get encircled
himself in 1972 in Mathematics ?
Some people are curious to know, how did this student of Zoology enter
and entrench himself in this field of mathematics. Here is a brief narration:
This author loves book reading very much. One day in 1972, while reading an
encyclopedia he saw square, triangle, trapezium and so on and found constant
for circle alone in r2 and 2 r and such constant was not there for other
constructions. He questioned himself, “Why”. „Why‟ led to “Why not
without ” for circle too. He thought many days. One day he inscribed a
circle in a square and found the diameter of the inscribed circle and the side of
the superscribed square equal. He was surprised and felt happy that he got the
clue to make real, the question “Why not without ”. He thought and thought,
did many things, searched, studied, enquired fellow mathematicians, did
physical experiments, on-and-off, for next 26 years.
Being a government college teacher, he was transferred in the mean
time, from Piler (1971-81) to Kadapa, to Nagari, to Anantapur and finally to
Chittoor (in December 1995). No answer to his question of 1972.
He was 26 when question came, waited another 26 years and lost self
confidence. He was like a man swimming on the surface of the ocean looking
down and striving hard to take hold of the wanted pin with its visible blurred
image lying on the bottom of the ocean. Man looks up when he is helpless.
This was what happened to him also. He went to the nearby temple of Mother
Goddess Durga (at Chittoor) in 1998 and prayed to HER. He gave a word to
the goddess. “When he gets answer and succeed in finding formulas for the
v
area and circumference of circle without equal to 22/7, he will keep
himself away from receiving awards, royalties, positions and avoid
felicitation functions, meetings etc. on account of future discovery”.
Surprisingly, one Mr. Ramesh Prasad a physics teacher, next neighbor to this
author when discussed with him this long pending problem after the promise
to the Goddess before giving a clue he asked this author how did he had been
doing. The answer to him was, as inscribed circle, it is smaller in size
compared to the larger superscribed square – the concept of difference had
been a dominating point. With this answer, Mr. Prasad told this author to
look at the problem, at the concept of “ratio” also and not only the factor of
difference. This author received this idea of Mr. Prasad and that whole night
worked on the problem and prepared an article and was sent to the Indian
Institute of Technology, Kharghpur, Mathematics Department, next morning.
The department was impressed with the paper and cautioned this author, was
not 22/7 and it was 3.1415926… in its reply with encouraging comments.
There, the search did not stop. Second question came anew. The new
question made this author why should there be 22/7, 3.1416, 3.1415926… By
March, 1998, during the rejuvenated search Gayatri Method, Siva method
came successively after many many many failures. Next 16 years,
continuous search has been focused on confirming, the correctness of 14 2
4
= 3.14644660942 as value. This author thanks the reader for this attentive
reading.

Pi treatment for the constituent rectangles of the superscribed
square in the study of exact area of the inscribed circle and its
value of Pi (SV University Method*)
R.D. Sarva Jagannadha Reddy
Abstract: Pi value equal to 3.14159265358… is derived from the Exhaustion method of Archimedes (240 BC)
of Syracuse, Greece. It is the only one geometrical method available even now. The second method to compute
3.14159265358… is the infinite series. These are available in larger numbers. The infinite series which are of
different nature are so complex, they can be understood and used to obtain trillion of decimals to
3.14159265358… with the use of super computers only. One unfortunate thing about this value is, it is still an
approximate value. In the present study, the exact value is obtained. It is 14 2
4
= 3.14644660942… A
different approach is followed here by the blessings of the God. The areas of constituent rectangles of the
superscribed square, are estimated both arithmetically, and in terms of of the inscribed circle. And value thus derived from this study of correct relationship among superscribed square, inscribed circle and constituent
rectangles of the square, is exact.
Keywords: Circle, diagonal, diameter, area, radius, side, square
I. Introduction
Square is an algebraic geometrical entity. It has four sides and two diagonals which are straight lines.
A circle can be inscribed in the square. The side of the square and the diameter of the inscribed circle are same.
This similarity between diameter and side, has made possible to find out the exact length of the circumference
and the exact extent of the area of the circle, when this interrelationship between circle and its superscribed
square, are understood in their right perspective. The difficulty is, the inscribed circle is a curvature, though, its
diameter/ radius is a straight line as in the case of side, diagonal of the square. When we say a different approach is adopted, it means, these are entirely new to the literature of mathematics. The universal acceptance
to the new principles observed in the following method is a tough job and takes time. However, as the
following reasoning ways are cent percent in accordance with the known principles, understanding of the idea is
easy.
To study the different dimensions, such as, circumference and area of circle, constant is inevitable. Similarly, to understand perimeter and area of the square, 4a and a2 are adopted and hence, no constant similar
to circle is necessary in square. In the present study, the area of the square is divided into five rectangles. The
areas of rectangles are calculated in two ways: they are: 1. Arithmetical way and 2. In terms of of the
inscribed circle. Finally, the arithmetical values are equated to formulas having , and the value of is derived ultimately, which is exact.
II. Procedure
Draw a square and its two diagonals. Inscribe a circle in the square.
1. Square = ABCD, AB = Side = a
2. Diagonals = AC = BD = 2a
3. ‘O’ Centre, EF = diameter = side = a
4. The circumference of the circle intersects two diagonals of four points: E, H, F and G. Draw a parallel
line IJ to the sides DC, passing through G and F.
5. OG = OF = radius = a/2
6. Triangle GOF. GF = hypotenuse = OG 2 = a
22 =
2a
2 = GF
* This author studied B.Sc., (Zoology as Major) and M.Sc., (Zoology) during the years 1963-68 in the Sri
Venkateswara University College, Tirupati, Chittoor district, Andhra Pradesh, India. And hence this author
as a mark of his gratitude to the Alma Mater, this method is named after University’s Honour.

Area of the ABCD square = a2

and
S. No. 14 this is equal to S.No. 16 26. As the area of the corner region is equal to any one of the 4 bottomed rectangles,
then it is = 24
a4
(S.No. 20 & 21)
27. Then the sum of the areas of 4 bottomed rectangles

= 24 a
28. Finally,
Area of the uppermost rectangle DIJC
= Square area – 4 bottomed rectangles
= 2 2 2a 4 a 3 a
29. CJ length = 3 a
Side = AB = IJ = a
30. Area of the upper most rectangle DIJC
= CJ x IJ = 3 a a = 23 a
31. Thus, the areas of five rectangles which are interpreted in terms of above, are
Uppermost rectangle DIJC = 23 a
4 bottomed rectangles = 24 a
Area of the ABCD square
Uppermost rectangle + 4 bottomed rectangles
= 2 2 23 a 4 a a
Area of the inscribed circle
= Uppermost rectangle DIJC + 3 bottomed rectangles
= 2 2 243 a 3 a a

III. Conclusion
It is well known, that a2 is the formula to find out area of a square or a rectangle. In this paper besides
a2, formulae, in terms of , of the inscribed circle in a square, are obtained, and equated to the classical arithmetical values of a2. One has to admire the Nature, that, a circle’s area can also be represented exactly
equal, by the areas of rectangles, thus, the arithmetical values of these rectangles, are equated to that of a circle,
which thus give rise to new value 14 2

I. Introduction
The geometrical entitles and concepts such as circle, square, triangle, Golden Ratio have been studied
extensively. “The Golden Ratio is the ratio of two line segments „a‟ and „b‟ (when a < b) such that a b
b a b

The ratio a 5 1

Mysterious Number, Page 146).
Archimedes (240 BC) of Syracuse, Greece, called the area arbelos that is inside the larger semi circle,
but outside the two smaller semi circles of different diameters. By its shape it is also called as “a shoemaker‟s
knife”. The Golden Ratio and the arbelos of Archimedes are different concepts. But in this paper by the grace
of God, it has become possible to see that these two concepts too have an interesting and unexpected inter
relationship between each other (one). Further, this relationship has an extended relationship also with the circle
(two). It is a well known fact that there exists simple and understable relationship between circle and square
(three). As circle, square are related, their combined interrelationship has been extended to value also (four). There is, thus, a divine chain of bond (of four interconnecting relations) exists, among square,
circle, Golden Ratio, arbelos and value. (Here value means a true/ real/ exact/ line-segment based value.
The stress here, on the adjectives to , has become necessary, because 3.14159265358… of Polygon is attributed or thrust on circle. In other words, this number to circle is a borrowed number from polygon and its
existence thus can not be seen in the radius of the circle, naturally. However, the new value 14 2
4
=
3.14644660942… (unlike with official value 3.14159265358…) is inseparable with radius and is, here, humbly submitted to the World of Mathematics:
Area of the circle = 27r 2r
r r2 4
Circumference of the circle = 2r 2r
6r2
= 2r
In support of the above formulae, this paper also chooses and confirms that the real value is 14 2

II. Procedure
1. Draw a square ABCD. Draw two diagonals. Inscribe a circle with centre „O‟ and with radius 1
2,
equal to half of the side AB of the square, whose length is 1.
AB = Side = EN = diameter = 1
AC = BD = Diagonal = 2
2. E is the mid point of AD
AE = 1
2, AB = 1
Triangle EAB, EB = hypotenuse = 5

EH = 1
2; HB = EB – EH =
5 1 5 1

Golden Ratio = HB = 5 1

3. EN = Diameter = 1
EJ = HB = 5 1
2
= 0.61803398874…
JN = EN – EJ = 5 1
12
= 3 5
2
= 0.38196601126…
4. Draw two semicircles on EN. And one semicircle with EJ as its diameter, and second semicircle with
JN as its diameter.
5. So, the diameter of the EJ semicircle = Golden Ratio = 5 1
2
and
the diameter of the JN semicircle = 3 5
2
6. The area present (which is shaded) outside the two semicircles (of EJ and JN) and within the larger EN
semi circle, is called arbelos of Archimedes.
7. Draw a perpendicular line on EN at J which meets circumference at K.
KJ = EJ JN (this is Altitude Theorem)

8. Draw a full circle with diameter KJ. It has already been established that this area of the full circle is
equal to the area of the shaded region called arbelos.
9. To calculate the area of the arbelos we have the following formulas.
q d q

and
2h

where h = perpendicular line KJ = 5 2 = diameter of the circle LKM
h

to find a way to decide which number actually represents value.

(when a circle is inscribed in a square, or when a square is created from the four equidistant tangents on a
circle, the length of the circumference of the inscribed circle can be demarcated in the perimeter of the
superscribed square. It is called rectification of the circumference of the circle).
Part III (Area of the arbelos)
Let us calculate now the area of the arbelos with the known two values, official value and new one called
Gayatri value.
15. With official value
0.236067977494
=
3.141592653580.23606797749
4 = 0.18540735595
(S. No. 10)
x 0.05901699437 = 3.14159265358 x 0.05901699437 = 0.18540735594
(S. No. 11)
16. With Gayatri value
0.236067977494
=
3.146446609420.23606797749
4 = 0.18569382184
(S.No. 10)
0.05901699437 = 3.14644660942 x 0.05901699437 = 0.18569382183
(S.No. 11)
17. Finally, we obtain two different values representing same area of the arbelos of Archimedes.
Official value gives: 0.18540735595 and
Gayatri value gives: 0.18569382184 Which one is the actual value for the area of the arbelos ? The answer can be found in Part IV.
Part IV
18. In the Figure 1 we have Golden Ratio, HB equal to 5 1
2
= 0.61803398874
19. Let us divide area of the arbelos of S.No. 17 with the Cube of Golden Ratio =
3
5 1
2
and
multiply it with 16
14 2 of the formula, derived in the S.No.14, which finally gives the area of the square
ABCD, equal to 1.
The value that gives the exact area of the square equal to 1 is confirmed as the real value. Here, the
Golden Ratio decides, the real value, by choosing the correct area of the arbelos of Archimedes of S.No. 17

0.23606797748 14 2
= 0.18540735595

As the exact area of the superscirbed square is obtained, it is clear, therefore, that, the real value is 14 2
4
= 3.14644660942…
III. Conclusion
It is well known that there exists a simple relationship between circle and square. In the present study,
it is clear such simple relation also exists between Golden Ratio and arbelos of Archimedes. This paper
combines above two kinds of relations and decides the real value, as 14 2

= 3.14644660942…

Abstract: - value 3.14159265358… is an approximate number. It is a transcendental number. This number
says firmly, that the squaring of a circle is impossible. New value was discovered in March 1998, and it is
14 2

= 3.14644660942…….. It is an algebraic number. Squaring of a circle is done in this paper. With
this new value, exact area of the arbelos is calculated and squaring of arbelos is also done. Arbelos of
Archimedes chooses the real value.
Keywords: - Arbelos, area, circle, diameter, squaring, side
I. INTRODUCTION Circle and square are two important geometrical entities. Square is straight lined entity, and circle is a
curvature. Perimeter and area of a square can be calculated easily with a2 and 4a, where ‘a’ is the side of the
square. A circle can be inscribed in a square. The diameter ‘d’ of the inscribed circle is equal to the side ‘a’ of
the superscribed square. To find out the area and circumference of the circle, there are two formulae r2 and
2r, where ‘r’ is radius and is a constant. constant is defined as “the ratio of circumference and diameter of
its circle. So, to obtain the value for , one must necessarily know the exact length of the circumference of the circle. As the circumference of the circle is a curvature it has become a very tough job to know the exact value
of circumference. Hence, a regular polygon is inscribed in a circle. The sides of the inscribed polygon doubled
many times, until, the inscribed polygon reaches, such that, no gap can be seen between the perimeter of the
polygon and the circumference of the circle. The value of polygon is taken as the value of circumference of
the circle. This value is 3.14159265358…
In March 1998, it was discovered the exact value from Gayatri method. This new value is 14 2
4
=
3.14644660942.
In 1882, C.L.F. Lindemann and subsequently, Vow. K. Weirstrass and David Hilbert (1893) said that
3.14159265358… was a transcendental number. A transcendental number cannot square a circle. What is
squaring of a circle ? One has to find a side of the square, geometrically, whose area is equal to the area of a
circle. Even then, mathematicians have been trying, for many centuries, for the squaring of circle. No body could succeed except S. Ramanjan of India. He did it for some decimals of 3.14159265358… His diagram is
shown below.
Then the square on BX is very nearly equal to the area of the circle, the error being less than a tenth of an inch when the diameter is 40 miles long.

With the discovery of 14 2

= 3.14644660942… squaring of circle has become very easy and is done
here. Archiemedes (240 BC) of Syracuse, Greece, has given us a geometrical entity called arbelos. The shaded area
is called arbelos. It is present inside a larger semicircle but outside the two smaller semicircles having two
different diameters.
In this paper squaring of circle and squaring of arbelos are done and are as follows.
Squaring of inscribed circle
QD is the required side of square
Squaring of arbelos YB is the required side of square

As there are two values representing for the same area of the arbelos, let us verify, with the both the values, which is ultimately the correct one.

This process is done by understanding the actual and exact interrelationship among, 1. area of the ABCD
square, 2. area of the inscribed circle in ABCD square and, 3. area of the arbelos of Archimedes.
34. For questions “why”, “what” and “how” of each step, the known mathematical principles are
insufficient, unfortunately.
So, as the exact area of ABCD square equal to 1 is obtained finally with new value. The new value equal to
14 2
4
is confirmed as the real value. This is the Final Judgment of arbelos of Archimedes.
III. CONCLUSION This study, proves, that squaring of a circle is not impossible, and no more an unsolved geometrical problem.
The belief in its (squaring of circle) impossibility is due to choosing the wrong number 3.14159265358… as
value. The new value 14 2
4
has done it. The arbelos of Archimedes has also chosen the real value in
association with the inscribed circle and the ABCD superscribed square.

Aberystwyth University Method for derivation of the exact π value
R.D. Sarva Jagannadha Reddy Abstract - Polygon’s value 3.14159265358… of Exhaustion method has been in vogue as ππππ of the circle for the last 2000 years. An attempt is made in this paper to replace polygon’s approximate value with the exact ππππ value of circle with the help of Prof. C.R. Fletcher’s geometrical construction.
Keywords: Circle, diagonal, diameter, Fletcher, ππππ, polygon, radius, side, square
I. INTRODUCTION
The official π value is 3.14159265358… It is considered as approximate value at its last decimal place, always. It implies that there is an exact value to be found in its place. a2, 4a, ½ab etc are the formulas of square and triangle which are derived based on their respective line-segments. Similarly, radius is a line-segment and a need is there to have a formula with radius alone and without π. The following formulas are discovered (March, 1998) from Gayatri method and Siva method.

Draw a square ABCD. Draw two diagonals. ‘O’ is the centre. Inscribe a circle with centre ‘O’ and radius ½. Side of the square is 1. E, F, G and H are the midpoints of four sides. Join EG, FH, EF, FG, GH and HE. Draw four arcs with centers A, B, C and D and with radius ½. Now the circle-square composite system is divided into 32 segments of two different dimensions, called S1 segments and S2 segments. Number them from 1 to 32. There are 16 S1 and 16 S2 segments in the square and 16S1 and 8S2 segments in the circle.

From the diagram of Fletcher the area of the shaded segment cannot be calculated arithmetically. The diagram of the Siva method helps in calculating the area of the shaded segment. How ?
Shaded area of Fletcher is equal to two S2 segments 19 and 20 of Siva method.
This author, in his present study, has utilized radius/ diameter as usual, and a corner length, in addition, of the construction to find out the arithmetical value to the shaded area. A different approach is adopted here. What is that ? As a first step the shaded area is calculated using four factors. They are of Fig-2.

The study of this method is extended further to decide which π value is the real π value ?

LK is part of the diagonal along with the corner length KC.
So, in the Second step, an attempt is made to obtain the LK length, from the area of the shaded region. How ? Let us take the reciprocal of the area of the shaded region;

Then, this value when divided by 32, we surprisingly get KL length. It may be questioned ‘why’ one should divided that value. The answer is not simple. Certain aspects have to be believed, without raising questions like what, why and how at times.

i.e. 2 2

−=0.14644660942… and differs however with 0.14561851144… of official π from 3rd decimal
onwards. If this argument is accepted, the present π value 3.14159265358… is not approximate value from its last decimal place, but it is an approximate value from the 3rd decimal.
IV. CONCLUSION
From the beginning to the end of this method, various line-segments are involved. Professor Fletcher’s construction is analyzed arithmetically with the line-segments of the Siva method. This arithmetical
interpretation has resulted in the derivation of a new π value, equal to 14 2

−. The new value is exact,
algebraic number.

New Method of Computing value (Siva Method)
RD Sarva Jagannada Reddy
I. Introduction
equal to 3.1415926… is an approximation. It has ruled the world for 2240 years. There is a necessity
to find out the exact value in the place of this approximate value. The following method givesthe total area of
the square, and also the total area of the inscribed circle. derived from this area is thus exact.
II. Construction procedure Draw a circle with center ‘0’ and radius a/2. Diameter is ‘a’. Draw 4 equidistant tangents on the
circle. They intersect at A, B, C and D resulting in ABCD square. The side of the square is also equal to
diameter ‘a’. Draw two diagonals. E, F, G and H are the mid points of four sides. Join EG, FH, EF, FG, GH
and HE. Draw four arcs with radius a/2 and with centres A, B, C and D. Now the circle square composite
system is divided into 32 segments and number them 1 to 32. 1 to 16 are of one dimension called S1 segments
and 17 to 32 are of different dimension called S2 segments.

V. Both the values appear correct when involved in the two formulae a) Official value = 3.1415926…
b) Proposed value = 3.1464466… = 14 2

Hence, another approach is followed here to decide real value.
VI. Involvement of line-segments are chosen to decide real value.
A line-segment equal to the value of ( - 2) in S1 segment’s formula and second line-segment equal to the
value of (4 - ) in S2 segment’s formula are searched in the above construction.
a) Official : - 2 = 3.1415926… - 2 = 1.1415926….
Proposed : - 2 = 14 22

VII. Conclusion: This diagram not only gives two formulae for the areas of S1& S2 segments andalso shows two line-

Jesus Method to Compute the Circumference of A Circle and
Exact Value
RD Sarava Jagannada Reddy
I. Introduction The Holy Bible has said value is equal to 3. Mathematicians were not satisfied with the value. They
thought over. Pythagorean theorem came in the mean time. A regular polygon with known perimeter was
inscribed in a circle and the sides doubled successively until the inscribed polygon touches the circumference,
leaving no gap between them. Hence this method is called Exhaustion method. The value of the perimeter of
the inscribed polygon is calculated applying Pythagorean theorem and is attributed to the circumference of the
circle. This method was interpreted, first time, on scientific lines by Archimedes of Syracuse, Greece. He has
said value is less than 3 1/7.
Later mathematicians have refined the Exhaustion method and found many decimals. The value is
3.1415926… and this value has been made official.
From 15th
century (Madhava (1450) of South India) onwards infinite series has been used for more
decimals to compute 3.1415926 of geometrical method. Notable people are Francois Viete (1579), Van
Ceulen (1596), John Wallis (1655), William Brouncker (1658) James Gregory (1660), G.W. Leibnitz
(1658), Isaac Newton (1666), Machin (1776), Euler (1748), S. Ramanujan (1914), Chudnovsky brothers
(1989). The latest infinite series for the computation of value is that of David Bailey, Peter Borwein and
Simon Plouffe (1996) and is as follows:
0
1 4 2 1 1
16 8 1 8 4 8 5 8 6ii i i i i
Using above formula Yasumasa Kanada of Tokyo University, Japan, calculated trillions of decimals
to 3.1415926….. with the help of super computer.
Mathematics is an exact science. We have compromised with an approximate value. Hence, many
have tried to find exact value. This author is one among the millions. What is ? It is the ratio of
circumference of a circle to its diameter. However, in Exhaustion method, perimeter of the inscribed polygon is
divided by the diameter of the outside circle. Thus 3.1415926…. violates the definition of . This is about the
value of . Next, about the nature of . C.L.F. Lindemann (1882) has said is a transcendental number based
on Euler‟s formula 1 0ie . In Mathematical Cranks, Underwood Dudley has said “‟s only position in
mathematics is its relation to infinite services (and) that has no relation to the circle…. Lindemann proclaimed
the squaring of the circle impossible, but Lindemann‟s proof is misleading for he uses numbers (which are
approximate in themselves) in his proof”.
Hence, pre-infinite series – days of geometrical method is approached again to find out exact value
and squaring of circle. This author has struggled for 26 years (1972 to 1998) and calculated the exact value of
in March, 1998. The following method calculates the total length of circumference and thus the exact value
has been derived from it.
Procedure: Draw a square. Draw two diagonals. Inscribe a circle. Side = a,
Diagonal = 2a , Diameter is also = a = d.
1) Straighten the square. Perimeter = 4a
Perimeter – Sum of the lengths of two diagonals = 4 2 2a a = esp
esp = end segment of the perimeter of the square.
27
Jesus Method To Compute The Circumference Of A Circle And Exact Value
www.iosrjournals.org 59 | Page
2) Straighten similarly the circumference of the inscribed circle
3 diameters plus some length, is equal to the length of the circumference.
Let us say circumference = x.
Circumference – 3 diameters = x – 3a = esc
esc = end segment of the circumference of the circle.
3) When the side of the square is equal to „a‟, the radius of the inscribed circle is equal to a/2. So, the
radius is 1/8th
of the perimeter of the square.
4) The above relation also exists between the end segment of the circumference of the circle and the end
segment of the perimeter of the square.
Thus as radius 2
a
of the inscribed circle is to the perimeter of the square (4a), i.e., 1/8th
of it,
so also, is the end segment of the circumference of the circle, to the end segment of the perimeter
of the square.
So, the end segment of the circumference = 8
end segment of the perimeter of the square

of the circle. In fact, 3.1415926… is derived from the line-segment of the inscribed/ circumscribed polygon in
and about circle, respectively. Surprisingly, when any line-segment of the circle is involved two things
happened: they are 1. Exact value is derived and 2 that exact value differs from 3.1415926… from its 3rd
decimal onwards, being 3.1464466… Two geometrical constructions of Hippocrates of Chios, Greece (450
B.C.) and Prof. Alfred S. Posamentier of New York, USA, and Prof. Ingmar Lehmann of Berlin, Germany, are
the supporting evidences of the new value. They are detailed below.
Keywords: value, lune, triangle, area of curved regions
I. Introduction In the days of Hippocrates, value 3 of the Holy Bible was followed in mathematical calculations.
He did not evince interest in knowing the correct value of . He wrote a book on Geometry. This was the first
book on Geometry. This book became later, a guiding subject for Euclid’s Elements. He is very famous for
his squaring of lunes. Prof. Alfred S. Posamentier and Prof. Ingmar Lehmann wrote a very fine
collaborative book on . They have chosen two regions and have proved both the regions, though appear very
different in their shapes, still both of them are same in their areas. These areas are represented by a formula
2 12
r
. The symbol „r‟ is radius. , here must be, the universally accepted 3.1415926…
Every subject in Science is based on one important point. It would be its soul. In Geometry, the soul is
a line-segment. The study of right relationship between two or more line-segments help us to find out areas,
circumference of a circle, perimeters of a triangle, polygon etc. For example, we have side in the square, base,
altitudein the triangle. The same concept is extended here, to show its inevitable importance in the study of
two regions of Professors of USA and Germany. The lengths of the concerned line-segments have been arrived
at and associated with 2 12
r
. 3.1415926… does not agree with the value of line-segments of two regions.
However, the new value 3.1464466… = 14 2
4
has agreed in to-to with the line-segments of the two regions
of the Professors. This author does believe this argument involving interpretation of 2 12
r
with the line-
segments, is acceptable to these great professors and the mathematics community. It is only a humble
submission to the World of Mathematics. Judgment is yours. If this argument in associating line-segment with
the formula looks specious or superficial, this author may beexcused.
II. Procedure The two methods are as follows:
1. Hippocrates' Method of Squaring Lunes And Computation of The Exact Value
“Archimedes's procedure for finding approximate numerical values of (without, of course, referring
to as a number), by establishing narrower and narrower limits between which the value must lie, turned out to
be the only practicable way of squaring the circle. But the Greeks also tried to square the circle exactly, that is
they tried to find a method, employing only straight edge and compasses, by which one might construct a square
equivalent to the given circle. All such attempts failed, though Hippocrates of Chios did succeed in squaring
lunes.
Hippocrates begins by noting that the areas of similar segments of circles are proportional to the
squares of the chords which subtend them

Consider a semi-circle ACB with diameter AB. Let us inscribe in this semi-circle an isosceles triangle
ACB, and then draw the circular arc AMB which touches the lines CA and CB at A and B respectively. The
segments ANC, CPB and AMB are similar. Their areas are therefore proportional to the squares of AC, CB and
AB respectively, and from Pythagoras's theorem the greater segment is equivalent to the sum of the other two.
Therefore the lune ACBMA is equivalent to the triangle ACB. It can therefore be squared”.
The Circular arc AMB which touches the lines CA and CB at A and B
respectively can be drawn by taking E as the centre and radius equal to EA or EB.
AB = diameter, d. DE = DC = radius, d/2; F = mid point of AC
N = mid point of arc AC

With the guidance of the formulae of earlier methods of the author where a
Circle is inscribed with the Square, the formulae for the areas of ANC, CPB, ACM
and BCM are devised.
1. Area of ANC = Area of CPB =
2d 2 12 1

2. Area of AMB = Areas of ANC + CPB (Hippocrates)
3. Area of ACM = Area of BCM =

4. Area of ACB triangle = 1 d

5. According to Hippocrates the area of the lune ACBMA is equivalent to the area of the triangle ACB

From the above equation it is clear that the devised formulae for the areas of different segments is
exactly correct.
6. Area of AMB = Areas of ANC + CPB

From March 1998, there are two values. The official value is 3.1415926… and the new value is

9. Formulae a2, 4a of square and ½ab of triangle are based on side of the square and altitude, base of

respectively.

As the value 0.1464466… which is half of FC or HK is in agreement with the area value of A/B region
equal to 1.1464466… in decimal part, it is argued that new value equal to 114 2
4 = 3.1464466…
is exactly correct.
The decimals 0.1415926… of the official value 3.1415926… does not tally beyond 3rd
decimal with the half
the lengths of HK and FC, whose value is 0.1464466, thus, the official value is partially right. Whereas, FC
& HK are incompatible with the areas of A & B calculated using official value. Then, which is real, Sirs?
III. Conclusion 3.1415926… agrees partially (upto two decimals only) with the line-segments of curved geometrical
constructions. When these line-segments agree totally and play a significant role in these constructions a
different value, exact value 14 2

= 3.1464466… invariably appears. Hence,
14 2

is the true valueof

New Value: Its Derivation and Demarcation of an Area of
Circle Equal to 4
In A Square
R.D. Sarva Jagannadha Reddy
ABSTRACT: value is 3.14159265358… it is an approximation, and it implies the exact value is yet to be
found. Here is a new method to find the most sought after exact value. 3.14159265358… is actually is the value of inscribed polygon in a circle. It is a transcendental number. When line-segments of circle are involved
in the derivation process then only the exact value can be found. 14 2
4
= 3.14644660942… thus obtained
is an algebraic number and hence squaring of circle is also done in the second part (method-3) of this paper.
KEYWORDS: Circle, Diagonal, Diameter, value, Radius, Square, Squaring of circle
I. INTRODUCTION
METHOD-1: Computation of tail-end of the length of the circumference over and above three
diameters of the Circle
The Holy Bible has said value is 3. Archimedes (240 BC) of Syracuse, Greece has said value is
less than 3 1/7. He has given us the upper limit of value. In 3 1/7, 3 represents three diameters and 1/7
represents the tail-end of the circumference of the circle (d = circumference)
In March, 1998, Gayatri method said the value as 14 2
4
= 3.14644660942… and its tail-end of the
length of the circumference of a circle over and above its 3 diameters as equal to 1
2 2 4 when the diameter is
equal to 1.
1/7 of Archimedes = 0.142857142857…

2 2 4 of Gayatri method =

6.82842712474 = 0.14644660942…
In the days of Archimedes there was no decimal system, because there was no zero. Archimedes is
correct in saying the tail-end length of the circumference is less than 1/7. How ? Gayatri method supports
Archimedes’ concept of less than 1/7 by giving 1
6.82842712474. The denominator part of the fraction, is
actually, less than 7 of 1/7. He is a great mathematician. This fraction 1
6.82842712474 has become possible
because of the introduction of zero in the numbers 1 to 9 and further consequential result of decimal system of
his later period. If he comes back alive, with his past memory remain intact, Archimedes would say, what he
had visualized in 240 BC has become real.
II. PROCEDURE
Let us see how this tail-end value of circumference is obtained: Draw a circle with Centre ‘O’ and
radius a/2. Draw four equidistant tangents on the circumference. They intersect at four prints called A, B, C

and D, creating a square ABCD. The diameter of the circle EF is also equal to the AB side of the square. Draw
two diagonals AC and BD. Their values are 2a . Perimeter of the square is equal to 4a.
In this circle-square composite system there are now 3 types of straight lines and one circumference
which is a curvature. The straight lines are 1. Perimeter of the square, 2. Two diagonals and 3. Diameter of the
circle. The values of these straight lines are known and exact. The length of the circumference is unknown and
hence this method is to find out its exact length with the help of known lengths of three types of straight lines.
Let us repeat here again the perimeter (4a) of the square and the sum of the lengths of two diagonals
2 2a are the outcome of the tangents on the circumference. It is clear therefore that the curved
circumference reflects its true length in all the straight lines of square and circle.
We know very well that there are three diameters and some length called tail-end in the circumference.
Circumference = 3 diameters + tail end length
Tail-end length is unknown and hence it is called x.
3d + x = circumference
Diameter is equal to side of the square i.e. d = a
Let us rewrite 3d + x as 3a + x
To find out the length of the x
We take the help of all the straight lines. The reciprocal of the two diagonals plus the perimeter of
the square and when this product is multiplied by the square of the diameter (= side), will give x value.
21 1x a a

Circumference = 3 diameters (3a) + tail-end length (x) = 1 14 2

The length of the circumference is obtained by superscribing a square. The correct understanding of
the relationship among perimeter, diagonals of the square and the diameter of the circle (= side of the square)
results in knowing the exact length of the tail-end of the circumference (x), what the great mathematician
Archimedes has said is less than 1/7 is proved now to be 1 1
6.828427124742 2 4

METHOD-3: DEMARCATION OF AREA OF CIRCLE WITH ITS STRAIGHT-LINED BOUNDARY
From Gayatri method, the world came to know in March 1998, for the first time, the length of the
circumference of the inscribed circle, demarcated in the perimeter of the square. The demarcated length of the
circumference of the circle is BA + AD + DC + CH = a + a + a + 2 2 14 2
a a4 4
The area of the circle is now bounded by a curvature called the circumference. In this method this area
can have a straight-lined boundary. In this process the value of plays important role. The official value is
3.14159265358… With this value let us locate the area:
1. Square = ABCD, Side = AB = a; AC = BD = diagonals = 2 a ; O = Centre
2. Inscribed a circle with centre O and radius = a

7. Let us try to demarcate the extent of area of the inscribed circle with the help of official value

Pythagorean way of Proof for the segmental areas of one square
with that of rectangles of adjoining square
R. D. Sarva Jagannadha Reddy 19-9-73/D3, Sri Jayalakshmi Colony, S.T.V. Nagar, Tirupati – 517 501, A.P., India
Abstract: It is universally accepted that 3.14159265358… as the value of . It is thought an approximation, at
its last decimal place. It is a transcendental number and squaring a circle is an unsolved problem with this
number. A new, exact, algebraic number 14 2
4
= 3.14644660942… is derived and verified with a proof that
is followed for Pythagorean theorem. It is proved here squaring of circle and rectification of circumference of a
circle are possible too.
Keywords: Pythagorean thorem, circle, square, .
I. Introduction
Official value is 3.14159265358… It is obtained from the Exhaustion method, which is a geometrical
method. This method involves the inscription of a polygon in a circle and increased the sides of the polygon,
until the inscribed polygon touches the circle, leaving no gap between them. The value 3.14159265358… is
actually the length of the perimeter of the inscribed polygon. And it is not the value of circle. There was no
method till yesterday to measure the circumference of a circle, directly or indirectly.
3.14159265358… has four characteristics: 1) It represents polygon, 2) It is an approximation, 3) It is a
transcendental number and 4) It says squaring a circle is impossible. And such a number is attributed and
followed as of the circle based on limitation principle, because of the impossibility of calculating, the length
of the circumference of circle and in such a situation this field of mathematics has been thriving for the last 2000
years.
From 1450 Madhavan of South India and a galaxy of later generations of mathematicians have
discarded geometrical construction and have introduced newly, the concept of infinite series.
In this paper geometrical constructions are approached again, for the derivation of value. New value has
been derived. It is 14 2
4
= 3.14644660942… It is an exact value, an algebraic number and makes squaring
of circle possible and done too.
II. Procedure
Siva method for the area of the circle of 1st square ABCD
Construction procedure
Draw a square ABCD. Draw two diagonals. ‘O’ is the centre.
Inscribe a circle with centre ‘O’ and radius ½. E, F, H and J are
the mid points of four sides. Join EH, FJ, FH, HJ, JE and EF.
Draw four arcs taking A, B, C and D as centres and radius ½.
Now the circle square nexus is divided into 32 segments. Number
them 1 to 32. 1 to 16 segments are called S1 segments. 17 to 32
segments are called S2 segments. 17 to 24, S2 segments are
outside the circle. 25 to 32, S2 segments are inside the circle.
Draw KP, a parallel line to the side DC which intersects diagonals
at M and N.
Square = ABCD
Side = AB = 1 = EH = diameter
Areas of S1 and S2 segments S1 = 6 2

Fig-1: Segmental areas calculated; Fig-2: Areas of Rectangles are calculated
Both values are same
This method is taken from the book Pi of the Circle of this author (available at
www.rsjreddy.webnode.com).
In this method there are two squares of same sides. First square has an inscribed circle divided into 32
segments of two dimensions called S1 and S2 segments, each category of 16 in number. And areas of these
segments are calculated using the following two formulas
2

aS 2
32 and

aS 4
32
which are obtained by solving two equations (in Square 1)
16 S1 + 16 S2 = a2 = Area of the square (Eq.1)
16 S1 + 8 S2 = a2/4= Area of the inscribed circle (Eq.2)
This method is called as Siva method. In the present method: Siva Kesava method, second square is
joined to the 1st square. One side CB is common to both the squares.
The second square is similarly divided, as in the case of 1st square, into 32 rectangles. Rectangles are also of
two dimensions each category of 16 numbers. The areas of each type of rectangle is equal to S1 and S2 segments
of the 1st square. These rectangles are formed, based on the division of common side of the both the
squares. The areas of rectangles agree cent percent with the above two formulas of Siva method, where
value is 14 2
4
. Thus, the division of 1
st square is exactly duplicated in the second square, except for the
difference, in the 1st square, 32 segments are curvy linear, and in the 2
nd square, 32 segments are rectangles,
naturally, of straight lines.
Now let us see how the common side CB is divided.
1. Squares 1 = ABCD, 2 = BZTC
2. Side = diameter of the inscribed circle = 1
3. KP = Parallel side to the side DC
4. OM = ON = radius ½

13. 2nd
Square BZTC is divided horizontally into four parts: CS, SQ, QR and RB.
14. Now BZ side of 2nd
square is divided into 8 parts. So, each length is 1/8.
15. Finally, the 2nd
square is divided into 16 rectangles of one dimension equal in area to S1 segments of 1st
square and 16 rectangles of 2nd
dimension, equal in area to S2 segments of 1st square.
16. Square BZTC consists of first two rows are of S1 and 3rd

rows are of S2 segments.
17. Area of each rectangle = S1 segments of 1st square =

In the first square we have seen that the length of the circumference of the inscribed circle is the outer edge of
the 16 S1 segments. In the 2nd
square also the outer edges of the 1st and 2
nd rows of 16 rectangles are equal to
14 2

.
26. Thus, Siva Kesava Method supports the value 14 2

obtained by earlier Gayatri, Siva, Jesus
methods.
27. And also, the curvy linear 16S1 and 16S2 segments of 1st square are all squared in the 2
nd square.
III. Conclusion
Two squares of same sides are drawn with one common side. Circle is inscribed in one square. Areas
of square and its inscribed circle are calculated from their constituent curvy linear segments. The correctness of
areas of constituent segments are verified with that of the areas of rectangles of the adjoining square. All the
values thus are proved correct.

To Judge the Correct-Ness of the New Pi Value of Circle By
Deriving The Exact Diagonal Length Of The Inscribed Square
R.D. Sarva Jaganndha Reddy
ABSTRACT : Circle and square are soul and body of the subject of Geometry. All celestial bodies in the
Cosmos are spherical in shape. Four equidistant tangents on a circle will give rise to a square. A circle can be
inscribed in a square too. Thus, circle and square are two inseperable geometrical entities. is a fundamental
mathematical constant. The world believes 3.14159265358… as value for the last 2000 years. Yet it is an
approximate value. Continuous search for its exact value is going on, even now. God has been kind. The exact
value is not a myth. It has become real with the discovery of 14 2
4
. It is a very tough job to convince the
world that the new finding is the real value. In this paper, the exact length of the diagonal of the inscribed
square form the length of an arc of the superscribed circle is obtained as a proof.
KEYWORDS: Circle, circumference, diameter, diagonal, perimeter, square
I. INTRODUCTION The geometrical constant, called , is as old as human civilization. In the ancient days, contributions
on was very admirable from the Eastern parts of the World. The Founding Father of Mathematics:
Hippocrates of Chios (450 BC) has not touched the value of . But his work on the nature of circular entities
such as squaring of lunes, semicircle and full circle is unparalled in the History of Mathematics.The present
value, 3.14159265358… could not understood Hippocrates’ work and its greatness. What is the reason ? This
number is not the of the circle. It is the value of the polygon. It was derived using Pythagorean theorem.
Pythagorean theorem gives exact length to a hypotenuse which is a straight line. Circumference of a circle is
not a straight line. It is a curvature. Hence, 3.14159265358… of polygon has failed to understand the greatness
of Hippocrates. In other words, 3.14159265358… is not a number at all.
After a long waiting of 2000 years by trillions of scholars NATURE has revealed its true length of a
circumference of circle and its value. The value is 14 2
4
= 3.14644660942… derived from Gayatri
method. It was discovered in March 1998. This worker is the first and fortunate humble man to see this
fundamental truth, and at the same time, made this author responsible to reveal to the whole world, its total
personality. He was cautioned by the Nature, through Inner Voice, further, not to shirk his responsibility till the
end, till the world welcomes it, and continue to search speck by speck naturally, respecting the Cosmic mind
of the Nature, with indomitable determination, and fight single handedly against the conservative attitude and
die like a warrior defeated, if situation of “reluctance to acceptance” still persistsFrom the remote past to the
present, the period of study of is divided into two periods: the period of geometrical dependence in the
derivation of value and the 2nd
period from 1660 AD onwards till today, the period of dependence on infinite
series,
dissociating totally geometrical analysis in the derivation of value. In the present and second period, the
number 3.14159265358… is considered as a number only and nothing to do with the definition of “the ratio of
circumference and diameter of a circle”. The paradox is, geometry is forgotten in the derivation of value but
searched for the same, in squaring of a circle. Finally, this number 3.14159265358… has gained four
characteristics: 1. Though it is a polygon number, established itself as a number of circle. 2. Though an
approximate number it ruled the world for many centuries as a final value. 3. Though it doesn‟t belong to a
circle has commented „squaring of circle‟ as an unsolved geometrical problem. 4. Though it has gained a status
of transcendental number with the definition of “…the fact that cannot be calculated by a combination of the
operations of addition, subtraction, multiplication, division, and square root extraction…” (Ref.1) is derived
actually in Exhaustion method, applying the Pythagorean theorem, and invariably with the involvement of 3 .
Further, the moment this number discared the association of Geometry, it has started a new relationship in

Euler’s formula e i
+1 = 0 with unrelated numbers which are themselves approximate numbers. C.L.F.
Lindeman (1882) has called number as a transcendental number based on Euler‟s formula. Here again, there
is a discrepancy in choosing , in the Euler‟s formula. In the formula, means radians 1800 and not,
constant 3.14… Are they both, radians and constant are identical ? constant is divine, whereas radians
equal to 1800 is, human creation and convenience. In the Euler‟s formula radians 180
0 is involved and the
resultant status of transcendence has been applied to constant. Let us rewright ei
+ 1 = 0 as
1 3.14e 1 0 . Is it right and acceptable ?It may not be wrong in calling that 3.14159265358… is a
transcendental number but it is definitely wrong when number is called a transcendental number and with a
consequential immediate statement “squaring of a circle” is impossible. The major objection is, the very
definition of is “the ratio of circumference and diameter of a circle”. So, this discrepancy led to the conclusion
that 3.14159265358… is not, infact, a number.In its support, we have the work of Hipporcrates. Hippocrates
had squared a circle even before any text book on Mathematics was born; His text book is the basis of Euclid’s
Elements too. As Hippocrates did square the circle it implied an algebraic number. Further, Lindemann is
also right in calling 3.14159265358… as transcendental number and not right, if he calls number as
transcendental. Here, there is a clarity of opinion thus. 3.14159265358… is a polygon number (and attributed
to circle).
In this paper the diagonal length is obtained from the actual length of the circumference of the circle.
II. PROCEDURE
Draw a square ABCD. Draw two diagonals AC and BD. „O‟ is the centre.
AB = Side = a; AC = BD = diameter = 2a

[10] The 2 value is 1.41421356237…
[11] It is clear therefore, that the value 3.14159265358… does not give exact length of the diagonal AC of

III. CONCLUSION In circle, there are circumference, radius and diameter. In square, there are perimeter, diagonal and
side. When a circle is superscribed with the square, circumference, side, diagonal and perimeter of square co-
exist in an interesting relationship. In this paper, this relationship is studied and the diagonal length is obtained
from the arc of the circumference. This is possible only when the exact length of the circumference is known.
A wrong length of circumference obtained using a wrong value gives only wrong length of diagonal.

The Natural Selection Mode To Choose The Real Pi Value Based
On The Resurrection Of The Decimal Part Over And Above 3 Of
Pi (St. John’s Medical College Method)

Physiology in St. John’s Medical College, Bangalore, India
Abstract: 22
7, 3.14, 3.1416, 3.14159265358… are being used as values at school–level–calculations and at
the research-level calculations. Many more numbers are found in the literature for . A method, therefore, is
necessary to decide which number is, the real value. The following method chooses 14 2
4
=
3.14644660942… as the real value.
Keywords: Circle, corner area, diameter, side, square.
I. Introduction Circle and square are basic geometrical constructions. To find out perimeter and area of a square there
are present two formulae 4a and a2, where ‘a’ is the side of the square. Similarly, to calculate the circumference
and the area of a circle, there are two formulae, 2r and r2, where ‘r’ is the radius and is a constant. The
concept represents, the ratio of the circumference and the diameter of its circle. Thus, the constant is a
natural and divine concept. We have radians equal to 1800, which is a human creation and convenience.
For the last 2000 years, 3.14159265358 …. has been ruling the mathematical world as the value. In
March 1998, a new value 14 2
4
=3.14644660942… was discovered by Gayatri method and supported by
more than one hundred different geometrical proofs in the last 16 years. The time now has come to decide,
which value, is present value or is new value, real ? Here is a simple procedure.
The nature has created a square and a circle. All the celestial bodies in the Cosmos are spherical in
shape. It shows the basic architectural design of the physical world from the Cosmic mind. We see on paper
that it has not only created an exact relationship between the circumference and the diameter of a circle and also,
the Nature has established an interesting relationship between square and its inscribed circle too. This
relationship is taken as the guiding principle to decide the real value from many numbers. Hence, this method is called the Natural Selection.

II. Procedure Draw a square. Inscribe a circle.

Area of the square = a2

Divide x by 32. In Siva method, it is found that when the circle – square composite geometrical
construction is divided symmetrically, the number of segments are 16 + 16 = 32

32 8
= - 3
Thus, we obtain finally, the formula 1
32 8 which is equal to the value over and above 3. As 2
of the diagonal of a square, so also 2 is for the circumference of the inscribed circle, and it is an established
fact by this work. And further, the number 32 represents a common associating factor of the inscribed circle
and the square.
The procedure followed here is in 4 steps.
Step 1, Calculates the areas of square and circle
Step 2, Obtains corner area by deducting circle area from the square area
Step 3, = Squarearea
Corner area and
Step 4, = Squarearea 1
Corner area 32
At the 1st step while calculating the area of the circle, known value is used. In this paper two values are chosen:
3.14159265358… the official value and
3.14644660942… the new value = 14 2
4
Any value enters at the 1st step, and it’s decimal part reappears at the 4th step. Thus, the resurrection of the
decimal part of value is observed at the 4th step. And this happens only when the real value is taken in the 1st step. Any other number, if used, does not reappear fully, at the 4th step.

An Alternate Formula in terms of Pi to find the Area of a
Triangle and a Test to decide the True Pi value (Atomic Energy
Commission Method*)
R.D. Sarva Jagannadha Reddy
Abstract: Circle, square and triangle are basic geometrical constructions. constant is associated with the
circle. In this paper, circle-triangle interlationship chooses the real value of and calculating the area of the
triangle involving of the inscribed circle. The alternate formula to find the area of the triangle is
23 3d
14 2
. This formula has a geometrical backing.
Keywords: Altitude, base, circle, diameter, perimeter, triangle
I. Introduction
The official value is 3.14159265358… It is an approximation, inspite of having trillions of its
decimals. A new value to was discovered in March 1998. The value is 14 2
4
= 3.14644660942… Both
the values have their own supporting arguments. Triangle is another geometrical entity. Its area is calculated using the formula ½ ab, where a = altitude and b = base. In this paper, a different formula has been derived to
find out the area of the equilateral triangle based on the of its inscribed circle. The formula ½ ab gives the area of the triangle. No other formula is necessary for the area of triangle. The main purpose of derivation of
new area formula of triangle is, to test the correctness of value involved in the new formula. One advantage in using the new formula for area of the triangle is, the resulting value tally’s exactly
with the value of ½ ab only, when the chosen value is correct one. If the wrong/ approximate value is involved in the new formula, it does not give exact value of the triangle. In other words, out of the two numbers
3.14159265358… and 14 2
4
= 3.14644660942… only one number, gives the exact area of the triangle.
The number which fails in giving exact value to the area of the triangle is decided as the wrong value.
Procedure
Draw a circle with centre ‘O’ and radius d
2. Draw three equidistant tangents on the circle. The tangents
intersect at A, B and C, creating an equilateral triangle ABC. DE is the hypotenuse of DOE triangle or the
chord of the circle.
Calculations:
Centre = O
Radius = OD = OE = d
2
Diameter = DF = d
Triangle = ABC
Side = AB = BC = AC = a = 3 d

So, official value 3.14159265358 has failed to give 3 3

otherhand, new value 14 2

has given
3 3

value 14 2

is the real value.
Equating conventional formulas ½ ab = 23

is itself a justification and a
naked truth of latter’s correctness.
II. Conclusion
½ ab is the formula to find out the area of a triangle. In this paper, a new formula 23 3
d14 2
is
derived. This formula by giving the exact area of ABC triangle shows, that circle and the equilateral triangle
are clearly interrelated and are not very different as we have been believing. The benefit we derive by using
this formula is, this formula chooses the real value, discarding other approximate values attributed to . This
method alone, for the first time in the history of mathematics, acts as a testing method of and boldly says
Archiemedes’ upper limit of 1

or 22
7 is a lower value compared to the real number.
Post script
As it is proved in this paper that the real value is 14 2
4
based on the area of the triangle ABC, it has made
possible to demarcate the length of the circumference of the inscribed circle in the straight-lined perimeter of
the ABC triangle. How ?
Let us know first the length of the circumference of the inscribed circle with the known value 14 2
4
Diameter = d
Circumference = d

When the diameter is equal to 1, the circumference = value
Let us search for the line-segments equal to 14 2

.
Diameter = DF = d
Altitude of ABC triangle = DC = 3d
2
Radius = OH = d
2
DE = hypotenuse = Chord = 2d

G is the mid point of DE
So, DG = GE = OG = 2d
4
OG = 2d

GH = Radius – OG = d 2d
2 4 =

CI = DC = 3d
2
IJ = GH = 2 2
d4
Circumference of the circle d = 14 2
d4
, So, the demarcated length DCJ in the perimeter of the ABC
triangle is equal to the circumference of the inscribed circle.
DC + CI + IJ = 3d 3d 2 2
d2 2 4
=

Thus the straight lined length equal to length of the curvature of the circumference of the inscribed circle is called rectification of circumference of a circle. It was done never before. People tried earlier in the
perimeter of the square but never in the perimeter of the triangle.

Abstract: Hippocrates has squared lunes, circle and a semicircle. He is the first man and a last man. S.
Ramanujan is the second mathematician who has squared a circle upto a few decimals of equal to
3.1415926… The squaring of curvature entities implies that lune, circle are finite entities having a finite
magnitude to be represented by a finite number.
Keywords: Squaring, lune, circle, Hippocrates, S. Ramanujan, , algebraic number.
I. Introduction Hippocrates of Chios was a Greek mathematician, geometer and astronomer, who lived from 470 until
410 BC. He wrote a systematically organized geometry text book Stoicheia Elements. It is the first book. And
hence he is called the Founding Father of Mathematics. This book was the basis for Euclid’s Elements.
In his days the value was 3 of the Holy Bible. He is famous for squaring of lunes. The lunes are
called Hippocratic lunes, or the lune of Hippocrates, which was part of a research project on the calculation of
the area of a circle, referred to as the „quadrature of the circle‟. What is a lune ? It is the area present between
two intersecting circles. It is based on the theorem that the areas of two circles have the same ratio as the
squares of their radii.
His work is written by Eudemus of Rhodes (335 BC) with elaborate proofs and has been preserved by
Simplicius.
Some believe he has not squared a circle. This view has become very strong with the number
3.1415926… a polygon‟s value attributed to circle, arrived at, from the Exhaustion method (EM) prevailing
before Archimedes (240 BC) of Syracuse, Greece, and refined it by him, hence the EM is also known as
Archimedean method. This number 3.1415926… has become much stronger as value, and has been
dissociated from circle-polygon composite construction, with the introduction of infinite series of Madhavan
(1450) of South India, and independently by later mathematicians John Wallis (1660) of England, James
Gregory (1660) of Scotland.
With the progressive gaining of the importance of 3.1415926… as value from infinite series, the
work of „squaring of circle‟ of Hippocrates has gone into oblivion. When the prevailing situation is so, in the
mean time, a great mathematician Leonhard Euler (1707-1783) of Switzerland has come. His record-setting
output is about 530 books and articles during his lifetime, and many more manuscripts are left to posterity. He
had created an interesting formula ei
+1 = 0 and based on his formula, Carl Louis Ferdinand Lindemann
(1852-1939) of Germany proved in 1882 that was a type of nonrational number called a transcendental
number. (It means, it is one that is not the root of a polynomial equation with rational coefficients. Another
way of saying this is that it is a number that cannot be expressed as a combination of the four basic arithmetic
operations and root extraction. In other words, it is a number that cannot be expressed algebraically).
Interestingly, the term transcendental number is introduced by Euler.
When all these happened, naturally, the work on the Squaring of circle by Hippocrates was almost
buried permanently.
This author with his discovery in March 1998 of a number 14 2
4
= 3.1464466… from Gayatri
method, and its confirmation as value, from Siva method, Jesus proof etc. later, has made the revival of the
work of Hippocrates. Hence, this submission of this paper and restoring the golden throne of greatness to
Hippocrates has become all the more a bounden duty of this author and the mathematics community.
II. Procedure I. Squaring of Lunes-(1)
Hippocrates has squared many types of lunes. In this paper four types of lunes are studied.
“Consider a semi-circle ACB with diameter AB. Let us inscribe in this semi-circle an isosceles triangle
ACB, and then draw the circular are AMB which touches the lines CA and CB at A and B respectively. The
segments ANC, CPB and AMB are similar. Their areas are therefore proportional to the squares of AC, CB and
56
Hippocratean Squaring Of Lunes, Semicircle and Circle
www.iosrjournals.org 40 | Page
AB respectively, and from Pythagora‟s theorem the greater segment is equivalent to the sum of the other two.
Therefore the lune ACBMA is equivalent to the triangle ACB. It can therefore be squared.”
The circular arc AMB which touches the lines CA and CB at A and B respectively
can be drawn by taking E as the centre and radius equal to EA or EB.

11. “Let ABC be an isosceles right angled triangle
inscribed in the semicircle ABOC, whose centre is O. On
AB and AC as diameters described semicircles as in the
figure. Then, since by Ecu. I, 47,
Sq. on BC = Sq. on AC + Sq on AB.
Therefore, by Euc. XII, 2,
Area semicircle on BC = Area semicircle on AC + Area semicircle on AB.
Take away the common parts
Area triangle ABC = Sum of areas of lunes AECD and AFBG.
Hence the area of the lune AECD is equal to half that of the triangle ABC”.

“There are also some famous moonshaped figures. The best known
of these are the crescents (or lunulae) of Hippocrates. By the
theorem of Thales the triangle ABC in the first figure is right
angled: Thus p2 = m
2 + n
2. The semicircle on AB = p has the area
AAB = p2/8; the sum of the areas of the semicircles on AC
and BC is AAC+ABC= (n2 + m
2)/8 and is thus equal to AAB.
From this it follows that:
The sum of the areas of the two crescents is the area of the
triangle.”

IV. Squaring of circle
“Consider two concentric circles with common centre O and radii such that the
square of the radius of the larger circle is six times the square of the radius of
the smaller one. Let us inscribe in the smaller circle the regular hexagon
ABCDEF. Let OA cut the larger circle in G, the line OB in H and the line OC
in I. On the line GI we construct a circular segment GNI similar to the segment
GH. Hippocrates shows that the lune GHIN plus the smaller circle is
equivalent to the triangle GHI plus t he hexagon.”

V. Post Script The following are the points on which some thinking is necessary:
1. 3.14159265358… is accepted as value.
2. 3.14159265358… is a transcendental number.
3. As this polygon‟s value is accepted as of the circle, circle and its value have become transcendental
entities.
4. The concept of transcendental number vehemently opposes squaring of circle.
Latest developments
5. 14 2
4
= 3.14644660942… is the new value.
6. 14 2
4
is the exact value.
7. This number is an algebraic number, being the root of x2 – 56x + 97 = 0
8. Squaring of circle is done with this number.
Conclusion
9. Hippocrates did square the circle.
10. 3.14159265358… is a transcendental number – it is correct.
11. 3.14159265358… can not square a circle, - is also correct.
Final verdict
12. As Hippocrates did the squaring a circle, it amounts to confirming that circle and its value are algebraic
entities. It implies that as 3.14159265358… is a borrowed number from polygon and attributed to circle,
called a transcendental number, said squaring a circle an unsolved geometrical problem, the final verdict
is, all are correct, except one, i.e. attributing 3.14159265358 of polygon to circle. Hence
3.14159265358… is not a value at all.

Durga Method of Squaring A Circle
RD Sarva Jagannadha Reddy
Abstract: Squaring of circle is an unsolved problem with the official value 3.1415926… with the new value
1/4 (14- 2 ) it is done in this paper.
Keywords: Exact Pi value = 1/4 (14- 2 ), Squaring of circle, Hippocrates squaring of lunes.
I. Introduction Squaring a circle is defined as constructing a square having an area equal to that of a given circle. It is
also called as quadrature of the circle.
This concept has been there from the days of Rhind Papyrus (1800 B.C) written by a scribe named
Ahmes. Hippocrates of Chios (450 B.C) has squared lunes, full circle and semicircle along with lunes. He
fore saw the algebraic nature of the value. value 3.1415926… has failed to find a place for it in the squaring
of lunes. Though the World of Mathematics has accepted his squaring of lunes, they became silent for why
3.1415926… is a misfit in his constructions. Further, there is a false opinion that Hippocrates could not square
a circle. However, Hippocrates did square a full circle and a semicircle along with a lune. In both the cases –
squaring a lune, squaring a circle along with a lune – the new value, 14 2
4
has explained perfectly well the
constructions of Hippocrates. Thus the propositions of Hippocrates which remained theoretical all these 2400
years, have become practical constructions with the discovery of 14 2
4
. It is clear therefore, we have
misunderstood Hippocrates because, we believed 3.1415926… as the value of . I therefore apologize to
Hippocrates on behalf of mathematics community for the past mistake done by us. And to atone the
academic sin committed by us, I bow my head and dedicate the explained parts (for details: Pi of the
Circle, last chapter: Latest work, Pages from 273 to 281) to Hippocrates, in www.rsjreddy.webnode.com
James Gregory (1660) has said squaring of circle is impossible. His view has been confirmed by
C.L.F. Lindemann (1882) based on Euler’s formula ei
+1 = 0. Von K. Weiertrass (1815-1897) and David
Hilbert (1893) have supported the proof of Lindemann by their proofs.
S. Ramanujan (1913) has squared a circle upto some decimals of 3.1415926… Prof. Underwood
Dudley doesn’t accept Lindemann’s proof because this is based on numbers which are approximate in
themselves.
Now, the exact value is discovered. It is 1
14 24
. It is an algebraic number. The following is
the procedure how to square a circle.

The unsuitability of the application of Pythagorean Theorem of
Exhaustion Method, in finding the actual length of the
circumference of the circle and Pi
R. D. Sarva Jagannadha Reddy
Abstract: There is only one geometrical method called Exhaustion Method to find out the length of the
circumference of a circle. In this method, a regular polygon of known number and value of sides is inscribed,
doubled many times until the inscribed polygon exhausts the space between the polygon and circle as limit. In
the present paper, it is made clear, that the value for circumference, i.e. 3.14159265358…. of polygon,
attributing to circle is a lower value than the real value, and the real value is 14 2
4
= 3.14644660942
adopting error-free method.
Key words: Circle, corner length, diameter, diagonal, polygon, side, square.
I. Introduction
The Holy Bible has said value is 3. The formula for circumference of a circle is d, where is a
constant and d is the diameter. When the diameter is 1 the circumference is equal to value.
When, a hexagon is inscribed in a circle of ½ as its radius, the perimeter of hexagon is equal to 3. It
means, the circumference is greater than 3, because hexagon is an inscribed entity in the circle. With the unit
diameter of circle, circumference and/or value is exchangeable, because, both are represented by a single
number. There were many values for . 10 = 3.16… (Chung Hing, 250 AD), 142
45 = 3.155… (Wang Fau,
250 AD), 3.14159… (Liu Hui, 263 AD), 3.1415 (Aryabhata, 499 AD). From Francois Viete (1579) onwards
the value 3.1415926… has become an accepted value.
It is a well established fact that the value is 3.14159265358… However, two things which are
associated with this number have not satisfied some scholars of mathematics. They are 1. 3.14159265358… is a
borrowed number of polygon, attributed to circle, believing in the logic of limitation principle and being an
approximate number, made super computers too have failed to find the exact value and 2. Assertively, this
number has said, squaring a circle impossible, being it is a transcendental umber. High school students, now
and then ask, when mathematics is an exact science, how is it possible we have many values are being used, for
example 22
7, 3.14, 3.1416, 3.14159265358….
Nature has been kind. Exact value has been found at last. A few papers in support of the exact
value have been published (in Reference). Surprisingly the new value is struggling very hard still for its
approval. All the time, the work done on has been cited, saying, the past generation or the present workers
could not be wrong. Thus, the new value (through was discovered 16 years ago, in March 1998 is yet to be
accepted.
From March 1998, with the discovery of 14 2
4
= 3.14644660942, this worker has been struggling
to find evidences in support of new value, and also struggling much more in search of an error in the
derivation of 3.14159265358…
There are some similarities and some differences between present and new values.
The similarity is, in Exhaustion method a polygon is inscribed in a circle and in the new method a
circle is inscribed in a square.
The differences are many: 1. Present value 3.14159265358… represents the perimeter/ area of the
polygon and attributed to circle; the new value represents the area of the inscribed circle only in a square
(called Siva method in Reference). Here, square helps but does not lend its value to circle. 2. Present value is
derived applying Pythagorean theorem meant for straight lines. New value is derived adopting entirely a new
approach for which no previous proofs/ statements are available. 3. Present value is a transcendental number
and new value is an algebraic number. 4. Present value says squaring of a circle is an impossible idea and
66

whereas the new value squared a circle. It also, circled a square (i.e., constructing a circle whose
circumference and/or area equal to the perimeter and/ or area of a square respectively. For example, if the side
of a square is 1, the perimeter would be 4 and its area would be 1. Circling a square means we have to find out a
radius geometrically of circle whose length of the circumference is 4 and/ or area of the circle is 1.
In this paper, present value-to some decimal places – is obtained using the new value 14 2
4
,
showing, circle, polygon and square are not different geometrical entities and their interrelationship, if
understood correctly, may help in the derivation of present value from the new value also.
If this idea is accepted, an algebraic number like 14 2
4
is also, capable of giving rise to, a
transcendental number like 3.14159265358…. It leads to the creation of a new doubt, is 3.14159265358… is
really a transcendental number ?
There are 3 examples cited below, linking present and new values 3.14159265358… and
3.14644660942… = 14 2
4
.
To drive to the point an elaborate explanation is chosen and here and there repetitions too appear.

Example-2
Archimedes inscribed a polygon of 96 sides with the circle and gave perimeter of the polygon as equal
to 3 10/71 = 3.140845… When the diameter of the superscribed circle is 1 unit, the perimeter = value. Prof.
Constantine Karapappopulos of University of Patra, Patra, Greece has suggested a formula for the
Archimedian minimum as equal to 1 3

in the range of 10

is obtained by the calculation method. One need not set aside it on the reason that the
above factor is based on the calculation method. This factor or circle connecting link can be viewed as a clue
or guiding factor for further analysis. On close observation one finds the denominator and the numerator of the
link are symmetrical and give us a right relationship between the inscribed polygon and the superscribed circle.
Example-3
Classical method involves the inscription of polygon in the circle. Starting with the known perimeter of a
regular polygon (here we start with a regular hexagon) of n sides inscribed in a circle, the
perimeter of the inscribed regular polygon of 2 n sides can be calculated by the application
of Pythagorean theorem. Let C be a circle with centre O and radius r, and let PQ = s be a
side of a regular inscribed polygon of n sides having a known perimeter. Then the apothem,
OM = u is given by
2
2 sr
2
hence the sagetta, MR = v = r – u is known. Then the
side RQ = w of he inscribed polygon of 2n sides is found from
2
2 sw v
2
hence the perimeter of this
polygon is known.

Let us analyse the above Table. The calculation is started with a regular polygon of 6 sides having the perimeter
equal to 3. The sides of polygon are doubled for 9 times and now the inscribed polygon has 3072 sides and its
perimeter = circumference of circle = value is equal to 3.141592067… Thus, the number of sides are
increased 512 times finally 3072
5126
. The length of the perimeter has increased from 1
62
= 3.000000
to 3.141592067… The correct value is 3.14159265358… From the above Table, it is possible to find the exact
length only upto 3.141592 i.e. 6 decimal places only with 3072 sides of the polygon.
ABCD = Square; EFGR = Circle; AB = Side = NQ = diameter = 1;
AC = Diagonal = 2 ; AN = QC = Corner length;
Diagonal – diameter = AC – NQ = 2 1 ; Hexagon = STGUVE
In the Classical method of calculating perimeter/ circumference/ in the above table, number of sides of the
inscribed polygon plays an important role. The derivation is started with 6 sides and ended with 3072 sides.
The perimeter of the hexagon is 3 and the perimeter of the polygon of 3072 sides has increased to

Starting no. of sides of the polygon = 6
Ending no. of sides of the polygon = 3072
Starting perimeter = 3
Ending perimeter = 3.141592067
Present value = 3.14159265358
New value = 14 2

= 3.14644660942…
In the following formula a relation is shown between two values: present value and new value as in the
above two examples.

The lengthy process involved in the above Exhaustion method is represented in a single formula 899 67 2
256
.
In the Exhaustion method Pythagorean theorem is applied. 3 invariably appears in every aspect of
calculation. The result 3.14159254422… obtained from the above formula using 2 is much more accurate at
7th
decimal place than what it is (3.141592067…) obtained in the Exhaustion method in the table.
In the Exhaustion method RQ is the hypotenuse and is the side of the inscribed polygon.
And in the above formula diagonal – diameter = corner lengths on either side of the diameter also play an
important role. Hence, it has become possible that the new value has given the present value (to some
decimals).
Let us understand, in much more clear terms, the above formula.
There are four factors in the Exhaustion method. They are
No. of sides of the hexagon = 6
Perimeter of the hexagon = ½ x 6 = 3
No. of sides of the final polygon = 3072
Perimeter of the final polygon = 3.141592067
1. Let us divide final sides by the sides of the beginning polygon i.e. hexagon 3072
5126
.
2. Let us divide corner length AN + QC into 512 parts.
AB = Side = NQ = Diameter = 1
AC = diagonal = 2
Corner length = AC – NQ = diagonal – diameter = 2 1
Let us divide above length into 512 parts = 2 1
512
= 0.00080901086
3. Multiply the above value with the no. of sides of the beginning polygon (hexagon) 2 1
6512
=
0.00485406516
4. Deduct the above value from the new value 14 2
4
= 3.14644660942 which gives the present
value (to some decimals).
14 2 6 2 6 899 67 2
4 512 256
= 3.14159254424
5. So, the corner length 2 1 is divided into 512 parts.

6. In this process corner length 2 1 is taken for consideration.
7. In the Exhaustion method the hypotenuse RQ in Fig.2 is taken for consideration and proceeded
successively for many times.
8. AC is the hypotenuse of the triangle DAC of Fig.2 and RQ is the hypotenuse of the triangle RMQ.
9. How does the length over and above 3 diameters of the circumference of the circle is arrived in
deriving the new value ?
The answer is very simple.
Let us divide the corner length QC only of Fig-2 by 2 and add to the 3 diameters.
Side = AB = diameter NQ = 1
Corner length QC = Diagonal diameter
2
= AC NQ 2 1
QC2 2
Divide QC by 2
= 2 1 1 2 1 2 2
2 42 2 2
Now, the length of circumference = 3diameters + 2 2
4
= 2 2 14 2
34 4
10. When we compare two ways of arriving the exact length of circumference of a circle, it is clear in
Exhaustion method the perimeter of the inscribed polygon is increased slowly by doubling the number of
sides of the previous polygon. Thus, the number of sides have been increased from 6 to 3072, it means it
has been increased 512 times. In other words, we have divided corner length into 512 parts.
In the second approach in the arrival of length of the circumference, the corner length is
divided at one stroke with 2 = Corner length QC
2
So, 3 sides + QC
2 =
2 1 13
2 2
= 14 2

11. Thus there are two values for the length of the circumference of the circle.
1. 3.14159265358… of Exhaustion method and
2. 3.14644660942… of Gayatri method
12. We can thus visualize a diagram of 2, containing a hexagon whose perimeter STGUVE is 3, next to
hexagon, 3.14159265358 of inscribed polygon of 3072 sides and further next and the circle EFGR, whose
circumference is equal to 3.14644660942… with radius ½.
III. Conclusion
There are now two values 3.14159265358… and 3.14644660942 … = 14 2
4
. In the Exhaustion
method, perimeter of the polygon is attributed to the circumference of the circle. As the inscribed polygon is
smaller one, the value 3.14159265358… must be lesser than the exact length of the circumference of circle.
This paper clearly shows the calculation error involved in the arrival of the actual length of the circumference
(= ) of the circle. Hence, Exhaustion method is not suitable in arriving the of the circle. However, this study
shows that both the values have a common-ness in their nature. In Exhaustion method while doing
calculations involving squaring, square root etc. and only a few decimals have been taken. All the numbers are
infinite numbers. So, the prolongation of round-off-error is universal throughout the calculations. And this
has resulted in a lower value 3.14159265358… instead of the actual value. However, the new work has tried to
overcome the error supposed to be in the Exhaustion method by adopting Gayatri method, Siva method, Jesus
