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×Vπh,d= 2×\sqrt \frac {V}{πh},

where:

  • dd is the diameter of a cylinder;
  • VV is the volume of a cylinder; and
  • hh 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=2×60π8=3.09d= 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!
