Spherical ring

Spherical ring definition

A ball ring is a solid ball that contains a cylindrical hole. It is bounded on the outside by a symmetrical spherical layer and on the inside by the lateral surface of a straight circular cylinder.

The volume only depends on the height L of the ball ring and not from the sphere radius R. This is plausible because the spherical ring becomes thinner as the spherical radius increases.
