Frequently Asked Questions
What is the formula?
V = ⅓ π r² h, Surface = π r (r + √(r² + h²))
What units should I use?
Use any single unit for all inputs. The area result is in that unit squared, and volume is in that unit cubed.
Can I use the result as an exact answer?
Treat it as an estimate or check unless the page and the rules that apply to you confirm otherwise. Rounding, fees and personal details can change the final result.
