What is the ratio formula for spheres

Similarly, the volume of a cube is V =L*L*L. So for a cube, the?ratio?of surface area to volume is given by the?ratio?of these?equations: S/V = 6/L. For a?sphere, surface area is S= 4*Pi*R*R, where R is the radius of the?sphere?and Pi is 3.1415... The volume of a?sphere?is V= 4*Pi*R*R*R/3.
