# Volume of a hollow cylinder Calculator

## Calculates the volume, lateral and surface areas of a hollow cylinder given two radii and height. | ||

- Purpose of use
- Calculate the surface area of a segment of a urinary catheter
- Comment/Request
- The formula for calculating the final surface area is wrong. It should be S = F + pi(r1^2 - r2^2) NOT S = F + 2pi(r1^2 - r2^2) becasue the surface area of a circle is pi*r^2, not 2pi*r^2
- from Keisan
- The hollow cylinder has a top surface and a bottom surface. (pi*r^2 * 2)

- Purpose of use
- Partial volume of a roll of paper

- Purpose of use
- To save me typing volume formula into calculator (because I''m lazy!)
