# Volume of Cone

To calculate the **volume of a cone** we need to know its diameter or radius, the pi number and its height. The **volume of a cone** means an amount of a space which a cone infills. For example, you can use this space to storage anything you want into a cone barrel or a cone can. The elementary unit of a volume is one cubic metre, it means the third power of one metre (1 m^{3}).

## Volume of Cone - formula

**Volume of Cone** = 1/12 × Ludolph's number × diameter^{2} × height of cone

or

**Volume of Cone** = 1/3 × Ludolph's number × radius^{2} × height of cone

V = 1/12 × (π × d^{2} × h) = 1/3 × (π × r^{2} × h)
