Diameter of a Cone Calculator

Math

The Diameter of a Cone Calculator finds the base diameter of a cone from its volume and height. Enter the volume and height.

Formula

r = √(3V ÷ (π·h)); Diameter = 2r
  • Derived from the cone volume formula V = (1/3)πr²h.
  • The diameter is twice the base radius.

Volume 314.16, height 10

Inputs
  • Volume: 314.16
  • Height: 10

r = √(3×314.16 ÷ (π×10)) = 5.48, so diameter ≈ 10.95.

Frequently asked questions

How do you find a cone's diameter from its volume?
Rearrange V = (1/3)πr²h to r = √(3V/πh), then double r for the diameter.
