Cone Volume Calculator
Calculate cone volume from radius and height.
How to Use the Cone Volume Calculator
Enter the cone radius and vertical height to calculate its volume.
Practical Example
A cone with a radius of 3 units and a height of 8 units has a volume of about 75.40 cubic units using V = (1/3)πr²h.
Factors That Affect the Result
Use consistent units, make sure you enter radius rather than diameter, and measure the vertical height accurately. The calculation assumes an ideal geometric cone.
Frequently Asked Questions
What is the cone volume formula?
V = (1/3)πr²h.
Can I enter diameter instead of radius?
Convert diameter to radius by dividing it by two before entering the value.
What unit is the result?
The result is in cubic units based on the length unit you enter.

Checking Cone Volume
Cone volume is one third of the volume of a cylinder with the same base and height: V = (1/3)πr²h. Radius and height must use the same unit before calculation.
The formula assumes a right circular cone. If you measure diameter, divide it by two to obtain radius. For containers or manufactured parts, wall thickness and unusable space can make practical capacity lower than the geometric volume, so distinguish between mathematical volume and working capacity.
