The equation a²z² = h2x2 + h-y2 is a cone with a point at the origin that opens upwards
(and down), such that at height z = h, the radius of the circle is a. Find the volume inside
this cone of height h and radius a at that height.
5. Find the volumes of two conical bodies, one bounded by the surface 2 = a y2 and
2 = 0, and the other bounded by the surfaces 2 = Vx+y2 and 2 = a. where a is a constant.
Try to solve this problem by doing each cone separately and then by calculating just one
