Find the volume v of the described solid s.

a) the base of s is an elliptical region with boundary curve 16x2 + 9y2 = 144. cross-sections perpendicular to the x-axis are isosceles right triangles with hypotenuse in the base.

b) the base of s is the region enclosed by the parabola y = 7 ? 7x2 and the x-axis. cross-sections perpendicular to the x-axis are isosceles triangles with height equal to the base.

c) the base of s is a circular disk with radius 2r. parallel cross-sections perpendicular to the base are squares.
