If the radius of the sphere is called R, the radii of the spherical segment bases are r1 and r2, and the height of the segment (the distance from one parallel plane to the other) called h, then the volume of the spherical segment is
The curved surface area of the spherical zone—which excludes the top and bottom bases—is given by
