# Volume of Cylinder

To calculate the **volume of a cylinder** we need to know its radius or diameter, the pi number and its height. The **volume of a cylinder** is a phrase which express a largeness of a space which a cylinder represents. It means a space which we can use for storage anything we want in a cylinder case. The elementary unit of a volume is one cubic metre, it means the third power of one metre (1 m^{3}).

## Volume of Cylinder - formula

**Volume of Cylinder** = 1/4 × Ludolph's number × diameter^{2} × height of cylinder

or

**Volume of Cylinder** = Ludolph's number × radius^{2} × height of cylinder

V = 1/4 × (π × d^{2} × h) = π × r^{2} × h
