Cylinder Volume Calculator
Multiply the base circle’s area by the height. Anything with a constant circular cross-section — cans, tanks, pipes — works this way.

Volume
942.48cm³
Litres
0.942L
Surface area
534.07cm²
Formula
Volume = π × Radius² × Height
Double the radius and volume quadruples: a cup twice as wide holds four times as much at the same height.
What to enter
| Input | Default | Accepted range |
|---|---|---|
| Radius (cm)Centre to edge — half the diameter. | 5 | 0 and up |
| Height (cm)The perpendicular height from the base — not the slanted side. | 12 | 0 and up |

| Litres (L)Capacity in litres; one litre is 1,000 cm³. | 0.942 |
| Surface area (cm²)The total area of a solid’s outer skin. | 534.07 |

Frequently asked questions
Q. How is Cylinder Volume Calculator calculated?
Volume = π × Radius² × Height — Multiply the base circle’s area by the height. Anything with a constant circular cross-section — cans, tanks, pipes — works this way.
Q. Can you walk through an example?
With Radius 5cm, Height 12cm, the answer is Volume 942.48cm³.
Q. What do I need to enter?
Enter Radius, Height. The result recalculates as you type, and an empty box counts as zero.
Q. How much does the answer move if I change a number?
Changing only Radius (cm) moves the answer to Radius (cm) 2.5 → Volume (cm³) 235.62 and Radius (cm) 10 → Volume (cm³) 3,769.91. The table below lays out five steps.
Q. How are the numbers rounded?
Money is shown to the nearest whole unit, percentages to one decimal place and everything else to two. What you see is rounded; the calculation itself carries the unrounded value forward.
Q. Anything to watch out for?
Double the radius and volume quadruples: a cup twice as wide holds four times as much at the same height.
