How it works

Multiply the circular base area by the perpendicular height.

FORMULA

Volume = π × radius² × height

A worked example

Radius 3 m and height 5 m give 45π ≈ 141.3717 m³.

Formula & detailed explanation

Right circular cylinder; radius and height nonnegative.

Calculations use decimal arithmetic with 40 significant digits internally. Choose 0–8 decimal places for the displayed result. Trailing zeros are omitted. Rounding affects only the displayed and copied result; very small values may round to zero. Accepted inputs have up to 100 characters and magnitudes from 10⁻¹⁰⁰ to 10¹⁰⁰, plus zero.
