<h3>How to determine the volume of the cone?</h3>
The volume of a cone is calculated using:

The parameters are not given.
So, we use the following assumed values
Radius, r = 5
Height, h =10
Using the assumed values, we have:

Evaluate the product

Hence, using the assumed values, the volume of the cone is
