Cylinder volume calculator
Calculator
The calculator needs JavaScript. The tables below give the same numbers for common cases.
How it is worked out
- Volume = πr²h; surface = 2πr(r + h).
- Volume = 282.743339 and surface area = 245.044227.
| Inputs | Answer |
|---|---|
| Radius: 3; Height: 10 | The cylinder has volume 282.743339 cubic units and surface area 245.044227 square units. |
| Radius: 5; Height: 20 | The cylinder has volume 1,570.796327 cubic units and surface area 785.398163 square units. |
| Radius: 0.5; Height: 1.2 | The cylinder has volume 0.942478 cubic units and surface area 5.340708 square units. |
How to use it
The volume of a cylinder is the area of its circular base times its height: V = πr²h. The total surface area is 2πr² for the two ends plus 2πrh for the curved side.
Use it for tanks, cans and pipes. If you know the diameter, halve it to get the radius.
