There is NO equation for the area of a sphere Assuming you mean surface area, the surface area of a sphere of radius r is 4πr^2.

V=4/3*Pi*r3 where r is the radius.

Surface area of a sphere = 4*pi*radius2

Use the formula for volume to solve for the radius of the sphere and then plug that radius into the formula for the surface area of a sphere.
