Conical Frustum Volume Calculator

If you ever wondered what’s the volume of a conical frustum, our conical frustum volume calculator is here for you. It can help you to calculate the volume of a conical frustum, given the top radius, bottom radius, and height. Also, thanks to this calculator you can determine the conical frustum volume and understand the formula behind.

Conical frustum volume formula

If you want to calculate the volume of a conical frustum, you can use the formula:

V = 1/3 * πh(r2 + rR + R2)

  • r: radius of the top surface
  • R: radius of the bottom surface
  • h: height of the conical frustum

Example of how to calculate the volume of a conical frustum

We now have the formula to calculate the volume of a conical frustum. Let’s look at a worked example.

For a conical frustum with the top radius r = 3 cm, bottom radius R = 4 cm and the height h = 5 cm, we can calculate the volume like so:

  • V = 1/3 * πh(r2 + rR + R2)
  • V = 1/3 * π * 5(32 + 3*4 + 42) = 193.73 cm3

Now you know how to find the volume of a conical frustum and the formula to apply. If you need a handy way to calculate the volume of any conical frustum, why not try out our conical frustum volume calculator?
