# 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
- Obtaining volume for hydraulic engine I'm constructing.

- Comment/Request
- what is the unit for volume in this calculator
- from Keisan
- If you put feet values, the unit of the result is ft^2 or ft^3. The unit of the result depends on the input unit.

Please refer to the FAQ

- Purpose of use
- Calculate the solid volume of a hollow tube of quartz glass so that I can estimate its mass (knowing density).
- Comment/Request
- Thank you.

- Purpose of use
- Calculate the volumes of cement needed to construct a foam cored fake piling for aquarium display.

- Purpose of use
- Math homwurk

- Purpose of use
- Calculate the needed volume of solder plated in a circuit board plated through hole that will result in 50% min fill after the reflow operation. Made an estimated of what the solder meniscus will look like after reflow.

- 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!)

- Purpose of use
- Engineering Calculations
