About the Cone Volume calculator
Find the volume of a cone from its base radius and height.
How to use the Cone Volume calculator
- Enter the Base Radius (r) and the Vertical Axis Height (h).
- Press Calculate Cone Volume.
Formula and method
V = (1/3) × π × r² × h. A cone holds one third of the volume of a cylinder with the same base and height.
Worked example
A cone with radius 3 and height 5 has a volume of about 47.12 cubic units.
Tips
- Height is measured straight up, not along the slanted side.
Frequently asked questions
What is the slant height?
The distance from the tip to the edge of the base along the surface, √(r² + h²).
