Compute the volume of a sphere from its radius using the classic formula, four thirds times pi times the radius cubed. For a radius of 5 the volume is about 523.6 cubic units. This calculator also returns the surface area of the sphere, which is four times pi times the radius squared, and the diameter for reference. A sphere is a perfectly round three dimensional shape, and the formula applies to balls, planets, bubbles, ball bearings and storage tanks. If you only know the diameter, halve it to get the radius before entering. Enter the radius in any unit and the volume returns in that unit cubed while the surface area is in the unit squared. The high precision value of pi and full floating point math run locally in your browser, so nothing leaves your device, and you can copy the volume result with a single click whenever you need it.
The volume is four thirds times pi times the radius cubed.
The surface area is four times pi times the radius squared.
Enter the radius, which is half the diameter, so divide a known diameter by 2 first.
Compute the volume of a sphere from its radius using the classic formula, four thirds times pi times the radius cubed. For a radius of 5 the volume is about 523.
