Frequently asked questions

Halve the diameter for the radius, then use 4/3 πr³. A 10-unit diameter gives a volume of about 523.6.

The radius is half the diameter, so a diameter of 10 has a radius of 5.

Volume grows with the cube of the radius, so doubling the diameter makes the volume eight times larger.

Cubic units of the diameter you enter, such as cubic centimetres.
