Volume of a Cone Calculator
Calculates the volume of a cone from the measurements you enter. Use any unit, as long as all inputs use the same one.
Result
- Volume
- 261.7994
How to use the volume of a cone calculator
- Enter the radius.
- Enter the height.
- The results update as you type, or press Calculate.
- Read the volume first, then the supporting figures below it.
Formula
πr²h ÷ 3
Worked example
For example, with these inputs:
- Radius: 5
- Height: 10
the calculator returns:
- Volume: 261.7994
Background
Each formula has assumptions built in. Area formulas assume flat shapes, volume formulas assume regular solids and statistical measures assume the data you enter is the data you want to describe. Knowing the assumptions helps you pick the right tool.
A quick mental estimate before calculating is a powerful check. If a room's floor area comes out at 4,000 square metres or a percentage comes out above 100% when it should not, you know to look again.
Frequently asked questions
How does the volume of a cone calculator work?
It applies this formula: πr²h ÷ 3
Can I use any units?
Yes, as long as every input uses the same unit. The answer will be in that unit (squared for areas, cubed for volumes).
