The surface area of a sphere is equal to four times pi times the square of the radius, and the volume of a sphere is equal to four-thirds times the cube of the radius.  Thus:

The surface area of a sphere is equal to four times pi times the square of the radius, and the volume of a sphere is equal to four-thirds times the cube of the radius.  Thus:

*SA=4πm²

*SA=4π''r''²

*V=1⅓πm³

*V=1⅓π''r''³

For any positive radius m.

For any positive radius ''r''.
