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
