Volume of a cone calculator

The following volume of a cone calculator will help you find the volume for any cone when the radius and the height are given.

Guidelines to follow when using the volume of a cone calculator

Just enter the values of the radius and the height and hit the calculate button.

Recall that the formula to get the volume of a cone is 1/3 × π × r ² × h
with π = 3.141592653589793

Therefore, the volume depends on the size of r and h. So, enter r and h in the calculator to get the volume.

The calculator will only accept positive value for r and h since a distance cannot be negative.

Some examples showing how to use the calculator to find the volume of a cone

Example #1:

A teepee, also called tipi, is a tent made of animal skins, canvas covering, or perhaps any other type of covering you see fit. Then, the covering is put upon wooden poles that come together like concurrent lines. The result is a geometric shape that looks like a cone. Use the calculator on this page to find the volume of a teepee if the base of the teepee has a diameter of 16 feet and the height is 10 feet.

First, we need to find the radius of the base.

Radius = diameter/2 = 16/2 = 8 

Enter 8 in the box that is labeled 'Enter the radius of the cone'

Enter 10 in the box that is labeled 'Enter the height of the cone'

Hit the button labeled 'Calculate'

The calculator will display 670.20, so the volume of the teepee is 670.20 ft³

Example #2:

An ice cream cone is shaped like an oblique cone. What is the volume of the ice cream cone if the base of the cone has a diameter of 3 inches and the height of the cone is 5 inches?

First, we need to find the radius of the base.

Radius = diameter/2 = 3/2 = 1.5 

Enter 1.5 in the box that labeled 'Enter the radius of the cone'

Enter 5 in the box that labeled 'Enter the height of the cone'

Hit the button labeled 'Calculate'

The calculator will display 11.78, so the volume of the ice cream cone is 11.78 in³
