Torus surface area and volume online calculator



App description

Calculation formula for the surface area and volume of the torus:

\(V=2πr^2R \cdot r^2\)

\(V= \frac {1}{4} π^2Dd^2\)

\(S=4πr^2Rr\)

\(S=π^2dD\)

\(S=39.478Rr\)

R——the average radius of the sphere

D——the diameter of the sphere

R——the radius of the torus

D——the average diameter of the torus

Usage example

Input data:

Average radius: 8

Section radius: 2

Click "Calculate" to output data

Surface area: 631.65

Volume: 631.65
