Circumscribed cylinder to a sphere. In 3 dimensions, the volume inside a sphere (that is the volume of a ball) is derived to be. where r is the radius of the sphere and Ï is the constant pi. Archimedes first derived this formula, which shows that the volume inside a sphere is 2/3 that of a circumscribed cylinder.
