Enter the radius of the funnel (in) and the height of the funnel (in) into the Funnel Volume Calculator. The calculator will evaluate and display the Funnel Volume. 

Funnel Volume Formula

The following formula is used to calculate the Funnel Volume. 

FV = 1/3*pi*r^2*h
  • Where FV is the Funnel Volume (in^3)
  • r is the radius of the funnel (in) 
  • h is the height of the funnel (in) 

To calculate a funnel volume, multiply the radius squared by the height, divide by 3, then multiply by pi.

How to Calculate Funnel Volume?

The following example problems outline how to calculate Funnel Volume.

Example Problem #1:

  1. First, determine the radius of the funnel (in).
    1. The radius of the funnel (in) is given as: 3.
  2. Next, determine the height of the funnel (in).
    1. The height of the funnel (in) is provided as: 10.
  3. Finally, calculate the Funnel Volume using the equation above: 

FV = 1/3*pi*r^2*h

The values given above are inserted into the equation below:

FV = 1/3*pi*3^2*10 = 94.24 (in^3)


Example Problem #2: 

For this problem, the variables needed are provided below:

radius of the funnel (in) = 4

height of the funnel (in) = 69

This example problem is a test of your knowledge on the subject. Use the calculator above to check your answer. FV = 1/3*pi*r^2*h = ?
