Formula

The Cylinder Radius from Volume Calculator uses the formula:

Radius = √(Cylinder volume ÷ (3.141592653589793 × Height))

Worked example

For example, with cylinder volume of 785.4 and height of 10, the radius is 5.0000.

Inputs used
Cylinder volume 785.4
Height 10
Results
Radius 5.0000

Key terms explained

Radius
The distance from the centre of a circle or sphere to its edge.
Volume
The amount of three-dimensional space an object occupies, measured in cubic units.

Frequently asked questions

Use radius = √(volume ÷ (π × height)). A volume of 785.4 over height 10 gives a radius of 5.

It rearranges V = πr²h to solve for the radius.

Yes. Volume alone is not enough; the height is required to find the radius.

The radius is in the length unit consistent with the volume and height you enter.
