How this calculation works
Calculate a cylinder’s volume and surface area from radius and height. Enter your values, select Calculate, then review the result. You can change any value and calculate again.
Formula used
Volume = πr²h · Surface area = 2πr(r + h)
Good to know
Results are estimates for informational purposes.
Example calculation
r = 3, h = 8 · volume = π × 3² × 8 ≈ 226.19
How to use this calculator
