Expert Advice On Impro...The spherical cap, also called the spherical dome, is a portion of a sphere cut off by a plane. The formula behind its volume is: volume = ( (π × h²) / 3) × (3r - h), or: volume = (1/6) × π × h × (3a² + h²), where the radius of the sphere is r, the height of the cap (the blue one) is h, and a is the radius of the base of the cap..
