Use this diameter of a cylinder calculator as an easy-to-use tool that calculates the diameter of a cylinder for you! The calculator can also come in handy if you're interested in the volume of a cylinder. If you're curious about the formula for the diameter of a cylinder and how to find the diameter of a cylinder, come along!

## How do I find diameter of a cylinder? The formula for diameter of a cylinder

To find the diameter of a cylinder, you can utilize the following formula:

$d= 2×\sqrt \frac {V}{πh},$

where:

• $d$ is the diameter of a cylinder;
• $V$ is the volume of a cylinder; and
• $h$ is the height of a cylinder.

For instance, if the volume of a cylinder is 60 cm³ and the height is 8 cm, the diameter of the cylinder in centimeters would be:

$d= 2×\sqrt \frac {60}{π8} = 3.09$

Looks cumbersome? Don't worry; the diameter of a cylinder calculator will do all the computations for you!
