# Volume of a torus Calculator

## Calculates the volume and surface area of a torus given the inner and outer radii. | ||

- Purpose of use
- Finding relative weights of potential parts of a kinetic sculpture

- Purpose of use
- Evaluate torus as ideal shape for closed environment of future cities. Rain capture, internal atmosphere and climate control, population density and mobility, regional adaptability for construction, other considerations.

- Purpose of use
- to help under stand how to find volume of different shapes

- Purpose of use
- Finding volume of a easy to buy void to reduce the volume of a water tank
- Comment/Request
- Is the volume answer in cubiic units?

- Purpose of use
- comparison of internal volumes of BMX tires, assumed to track elastic properties

- Purpose of use
- Decided to draw isometric sketches of shapes from online pages and the input units to find various calculations. This was all done out of boredom and I enjoy it.

- I had no idea that this site existed and am going to recommend this to others. Personally, I love looking at formulas as well. All I ask is the addition of a truncated torus and partial torus. what I mean is page for a torus but the cylinder that makes it up is like the cylinder on the "volume of a partial right cylinder" page, and another page for a torus but its cylinder does not wrap around all the way. The second one could just be "(torus formula) divided by degree of angle" or something like that, but I just would like to make sure. Thanks for the knowledge though!

- Purpose of use
- determine volume of o-ring

- thanks

- Purpose of use
- Calculating how long it might take to manually pump up one of the new 26 x 4 inch "fat tires" on an MTB.

- Purpose of use
- Volume of o ring.

- 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
