How it works
Use a right circular cone: its axis is perpendicular through the base centre. Slant length is the generator from apex to the base circle. This form solves for slant length; enter the known quantities in Volume, Radius.
Inputs and units
| Input | Example value | What to enter |
|---|---|---|
| Volume | 37.69911184307752 cm³ | Formula symbol: V. Required unit: cm³. Must be greater than zero. |
| Radius | 3 cm | Formula symbol: r. Required unit: cm. Distance from the centre to the edge; half the diameter. Must be greater than zero. |

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.
When can I use the slant length result?
Lengths use cm, areas cm² and volumes cm³ on one consistent scale. The positive real branch is selected; the supplied quantities must describe the stated shape.
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.
