How to use Cone Calculator

Enter the base radius and vertical height and the calculator returns the volume, slant height, lateral surface, base area and total surface area.

Frequently asked questions

How is a cone's volume calculated?

Volume = (1/3)πr²h — one third of the equivalent cylinder's volume.

What is the slant height?

The distance from the base edge to the apex, found with l = √(r² + h²).

What is the total surface area of a cone?

Total surface area = πr² + πrl, the circular base plus the lateral (slant) surface.
