How it works
Find the volume of a cone cut parallel to its base. The smaller radius cannot exceed the larger radius.
Inputs and units
| Input | Example value | What to enter |
|---|---|---|
| Larger radius | 5 | Enter a numeric value. Distance from the centre to the edge; half the diameter. Must be greater than zero. |
| Smaller radius | 3 | Enter a numeric value. Distance from the centre to the edge; half the diameter. Use a non-negative value. |
| Vertical height | 6 | Enter a numeric value. Must be greater than zero. |

- 5
- Smaller radius
- 3
- Vertical height

Reading the result
Enter lengths in the same unit. Area uses the square of that unit and volume its cube. Height is perpendicular to the base; use a sloping side only when the input explicitly asks for it.
Questions and answers
Can I use the example values for my own calculation?
The example values illustrate the calculation. Replace every input with your own information, especially dates, rates and the selected operation.
Why are some results rounded?
Results display up to 8 decimal places. Calculations use the unrounded values; very small values use scientific notation. JavaScript floating-point arithmetic can introduce tiny rounding differences.
Are my inputs sent to a server?
The calculator processes inputs in your browser. Its code does not send your values to a server.
