Use this calculator to find out the volume and area of a sphere using either the sphere's radius, diameter or circumference.
The area `A` of a sphere is calculated using the formula:
`A = 4pir^2`, where `r` is the radius of the sphere.
The volume `V` of a sphere is calculated using the formula:
`V = (4pir^3)/3`
If the diameter of the sphere `d` and the length of the circumference `C` are known, its area can be calculated (without the figure `pi`) using the formula:
and the volume using the formula:
`V = (Cd^2)/6`
