Frequently asked questions

Halve the diameter for the radius, then use πr²h. A 6-unit diameter and height 10 give about 282.74.

It is half the diameter, so a diameter of 6 means a radius of 3.

Multiply cubic metres by 1,000. The result here is in the cubic units you enter.

Use πr²h directly, or simply enter twice the radius as the diameter.
