Volume of a Spherical Cap

1/3πh² (3r - h)

Where:
r = radius of the cap
h = height of the cap

A spherical cap is a portion of a sphere that lies above or below one of its planes. If the plane lies on the center of the sphere, the cap is called a hemisphere (a hemisphere is one equal half of a sphere. For example, the north hemisphere of the earth extends from the equator to its very top point.)

The volume of a spherical cap tells how much space it occupies.
