Purpose of use
Volume of o ring.
Comment/Request
Enhancement suggestion. Calculating volume of O ring sold as 13.95 inside diameter and 2.62mm thickness required use of another calculator before use of torus calculator. 15mm by 2mm O ring can be done in my head before using Torus calculator

Purpose of use
As a demonstration tool
Comment/Request
Since o-rings are typically specified (& sold) by inside diameter and the cross section this would be a very useful (& time saving) option

Purpose of use
Checked against what I guessed would be the volume of a torus. My equation was longer, but this was the simpler version.

I guessed it was the radius of the torus, times the average of the circumferences.
Pi*[(b-a)/2]^2*[(2*Pi*b)+(2*Pi*a)/2]

Turns out I was right, and after factoring it out, I reduced it to the same equation.
Comment/Request
It's great. A note explaining that it is similar to calculating a cylinder, and that you are averaging the circumference to get the "length" would be nice.
