Volume of a Torus
\[V = 2\pi^2 R r^2\]

Variables

Vvolume (m³)
Rmajor radius (distance from center of tube to center of torus) (m)
rminor radius (radius of the tube) (m)

Description

What is this formula?

This formula calculates the volume of a torus (doughnut-shaped solid). It depends on the major radius (distance from center to tube center) and the minor radius (radius of the tube).


When to use it

Use this formula when calculating the volume of ring-shaped or toroidal structures.


Example

If a torus has:

R = 5 m

r = 2 m


V = 2π² × 5 × 2²

V = 2π² × 5 × 4

V = 40π²

V ≈ 394.78 m³
