How to Calculate Torus
What is Torus?
A torus is the 3D shape of a donut or ring. It is formed by rotating a circle of radius r around an axis at distance R from the circle's centre. The inner hole appears when R > r.
Formula
- R
- radius of the tube itself — radius of the tube itself
Step-by-Step Guide
- 1R = distance from the centre of the tube to the centre of the torus
- 2r = radius of the tube itself
- 3Volume = 2π² × R × r²
- 4Surface area = 4π² × R × r
