Find the center of mass of a solid of constant density bounded below by the paraboloid z = x^2 + y^2 and above by the plane z = 100. Then find the plane z = c that divides the solid into two parts of equal volume. This plane does not pass through the center of mass.
The answers in the back of the book are:.
(a) x-bar=y-bar=z-bar=(8/3)
(b) c=2(sqrt(2))
