How it works
Volume and lateral-only area must belong to the same right cylinder. Entering total surface as lateral area gives the wrong radius. This form solves for surface area; enter the known quantities in Volume, Lateral area.
Inputs and units
| Input | Example value | What to enter |
|---|---|---|
| Volume | 113.09733552923255 cm³ | Formula symbol: V. Required unit: cm³. Must be greater than zero. |
| Lateral area | 75.39822368615503 cm² | Formula symbol: L. Required unit: cm². 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 surface area 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.
