Cone Calculator

Calculate the volume, slant height, and surface area of a cone.

Volume
37.6991
Slant height
5
Surface area
75.3982

Enter the base radius and height to get a cone's volume (1/3·π·r²·h), slant height, and total surface area.

How to use

  1. Enter the base radius of the cone.
  2. Enter the vertical height.
  3. Read the volume, slant height, and surface area.

Frequently asked questions

What is slant height?
It is the distance from the apex to the base edge, equal to the square root of radius squared plus height squared.
How is cone volume calculated?
Volume equals one-third times pi times the radius squared times the height (1/3·π·r²·h).
