Work out cylinder volume instantly with clear inputs, formula shown and shareable results.
A cylinder is a prism with a circular cross-section, so its volume is base area times height: V = πr²h. The curved surface unrolls into a rectangle of width 2πr and height h.
Volume
V = πr²h
Lateral area
A = 2πrh
π × 9 × 10 = 90π ≈ 282.743339 cubic units.
Work in centimetres and divide the cubic-centimetre result by 1000, which is done for you above.
