Test 1 Math 266. ( NO calculator, 11 pt. each)
Find the area enclosed by y = 5x – x2 and y = x. Solve and Draw.
Sketch the region enclosed by x = 2y2 and y = x – 1, set up the integral for the area. Do not solve.
Set up the integrals for the volumes of solids of revolutionRevolve the following triangular templates about the following axes: x = 10, –10, y = 10, –10, find the R and r.
Set up the integral for the following volume shown in shaded region in the picture.
Set up the integral for the following volumea. The solid is a pyramid 60 feet high. The horizontal cross-section x feet from its top is a square of side 3x feet.
b. The solid is a pyramid 40 meters high. The horizontal cross-section x feet from its top is an equilateral triangle of side 6x meters.
c. The base of a solid is a circle of radius 6 cm. All the cross-sections perpendicular to a fixed diameter are equilateral triangles.
