# Calculate volume and surface area of Torus

• Last Updated : 07 Apr, 2021

Torus

Property:

2. It is not a polyhedron

3. It has no vertices or edges

• Surface Area
The surface area of a Torus is given by the formula –

`Surface Area = 4 × Pi^2 × R × r`
• Where r is the radius of the small circle and R is the radius of bigger circle and Pi is constant Pi=3.14159.

• Volume
The volume of a cone is given by the formula –

`Volume = 2 × Pi^2 × R × r^2`
• Where r is the radius of the small circle and R is the radius of bigger circle and Pi is constant Pi=3.14159.

Examples:

```Input : r=3, R=7
Output :
Volume: 1243.568195
Surface: 829.045464```
