Formula and methodology
Formula: Curved area = 2πr²; total area = 3πr²; volume = 2πr³/3.
A hemisphere is half a sphere; total surface area includes the flat circular base while curved area does not.
This result follows the calculator's declared inputs, precision, validation boundaries, and model limits.
Input contract
- Radius — length units; minimum 1.0E-6; maximum 1000000
Worked example
| Input | Value |
|---|---|
| Radius | 3 |
Curved area ≈ 56.549; total area ≈ 84.823; volume ≈ 56.549 cubic units.
Assumptions and limits
- The shape is an exact Euclidean hemisphere.
- Radius is positive and all outputs follow its length unit.
- Wall thickness, openings, and material are not modeled.
