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) 

To calculate the test tube volume, multiply the radius squared by pi, then multiply by the height.

How to Calculate Test Tube Volume?

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

Example Problem #1:

  1. First, determine the test tube radius (in).
    1. The test tube radius (in) is given as: 4.
  2. Next, determine the height (in).
    1. The height (in) is provided as: 50.
  3. 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 = ?
