Cylinder Volume Calculator
Cylinder volume calculator: volume, capacity in litres and surface area from radius and height.
V = π · r² · h
How to use this calculator
- Choose the quantity you want under “Solve for”.
- Type the known values and pick their units: any combination works.
- The result updates as you type. Open “Show the steps” to see the substitution.
V = π r² h. The surface area is 2πr(r + h).
Use it for tanks, pipes, cans and pools; 1 L = 1 000 cm³.
Formula
V = π · r² · h
