Enter the test tube radius (in) and the height (in) into the Test Tube Volume Calculator. The calculator will evaluate and display the Test Tube Volume.

## Test Tube Volume Formula

The following formula is used to calculate the Test Tube Volume.

**TTV = pi * tr^2*h**

- Where TTV is the Test Tube Volume (in^3)
- tr is the test tube radius (in)
- h is the height (in)

## How to Calculate Test Tube Volume?

The following example problems outline how to calculate Test Tube Volume.

Example Problem #1:

- First, determine the test tube radius (in).
- The test tube radius (in) is given as: 4.

- Next, determine the height (in).
- The height (in) is provided as: 50.

- Finally, calculate the Test Tube Volume using the equation above:

TTV = pi * tr^2*h

The values given above are inserted into the equation below:

TTV = pi * 4^2*50 = 2513.27(in^3)

Example Problem #2:** **

For this problem, the variables needed are provided below:

test tube radius (in) = 3

height (in) = 70

This example problem is a test of your knowledge on the subject. Use the calculator above to check your answer.

TTV = pi * tr^2*h** = ?**
