How this calculator works
Formula
Volume = (1/3) × π × r² × h, where r is base radius and h is height.
Worked example
r = 3 m, h = 9 m: volume ≈ 84.82 m³.
Assumptions to verify
- Standard geometric or arithmetic definitions apply.
- Inputs use the units you choose.
- Results are estimates, not professional advice.
