Enter the cylinder mass (kg), the radius (m), and the length (m) into the Cylinder Density Calculator. The calculator will evaluate and display the Cylinder Density. 

Cylinder Density Formula

The following formula is used to calculate the Cylinder Density. 

CD = m / (pi*r^2*L)

  • Where CD is the Cylinder Density (kg/m^3)
  • m is the cylinder mass (kg) 
  • r is the radius (m) 
  • L is the length (m) 

How to Calculate Cylinder Density?

The following example problems outline how to calculate Cylinder Density.

Example Problem #1

  1. First, determine the cylinder mass (kg).
    1. The cylinder mass (kg) is given as 350.
  2. Next, determine the radius (m). 
    1. The radius (m) is calculated as: 3.
  3. Next, determine the length (m). 
    1. The length (m) is found to be: 5.
  4. Finally, calculate the Cylinder Density using the formula above: 

CD = m / (pi*r^2*L)

Inserting the values from above yields: 

CD = 350 / (pi*3^2*5) = 2.475 (kg/m^3)


Example Problem #2

The variables needed for this problem are provided below:

cylinder mass (kg) = 500

radius (m) = 6

length (m) = 7

This example problem is a test of your knowledge on the subject. Use the calculator above to check your answer. CD = m / (pi*r^2*L) = (kg/m^3)
