Revision material
• Text: Semester Reviews (note: Semester Review questions were not set in the work schedules so you have probably not done these problems before).
� Statistics pg 792-794
� Probability pg 790-791
� Linear Relations pg 408-409
� Measurement pg 787-788
� Quadratic Equations pg 416-417
� Surds pg 412 (Q1-4) & 413 (Q1-3)
• 2021 Tests, Assignments and Quizzes – go back through these and write out corrected versions of any mistakes made. Copies of the tests will be uploaded to the learning site.
� 1. Statistics Test
� 2. Probability Test
� 3. Linear Relations Test
� 4. Measurement Test
� 5. Quadratic Equations Practice test
• Text chapter reviews
The chapter reviews at the end of each chapter provide a comprehensive review of the chapter. Each question is labelled with the relevant exercise that you can return to for more practice.
• Past Examinations (will be uploaded to the learning site)
� Semester 1 Technology Free examination
� Semester 1 Technology Active examination General notes
• You should attempt and follow up on questions early. Regular practice over the coming weeks will be more effective that “cramming” in the days leading up to the exams.
• It is most important that you have a well prepared summary book with material that may assist you with the technology active examination.
• Make sure that you have a charged calculator for the technology active examination and that you know how to use it. You should ensure you practice with your CAS calculator while revising.
• You must include some timed practice as a part of your revision. • Ensure you have made full corrections to all work handed back during the Semester and
seek support from your teacher with any areas where you’re still unsure.

Section B Extended Response Question 10 marks Include working throughout.
Obelisks were originally erected at the entrance to ancient Egyptian temples. Cleopatra’s Needle (depicted in the diagram below) can be found in Paris. Obelisks are designed with a square based pyramid for the cap (the top of the obelisk). This is then placed onto a section of another square based pyramid with a much steeper slant angle to make the lower part of the obelisk (the pillar).
Mr Davis wants to erect an obelisk at St Leonard’s College. This obelisk will have a pyramid shaped cap with a square base of side length 50 cm and a perpendicular height of 40 cm. The obelisk is to be made using concrete.
Question 1
a) Determine the volume of concrete required to create the cap.
Round your answer to the nearest cm3.
1 mark
b) The cap will be painted in gold paint. Determine the total surface area that will need to be painted.

The total height of the obelisk needs to be 8m with a square base of side length 1m.
c) Determine the height of the of the section of pyramid beneath the cap (the pillar).
1 mark
The pillar (lower part of the obelisk) is made from a section of a larger pyramid as shown:
d) The perpendicular height of the original pyramid used to make the pillar of the St Leonard’s College obelisk was 1520 cm. Calculate the volume of the concrete required for the pillar, rounding your answer to the nearest cm3.
