Tip #1
In the previous lesson, we learned that the volume of a cylinder is  πr2h. Now, the volume of a cone is one third of the cylinder's volume.

Hence, for a cone with height h and base radius r, the volume, V of the cone will be:
formula for the volume of a sphere
a cone with a height h and base radius r

where π is a number that is approximately equals to 3.14.

The math video below will give more explanation on this formula. Also, we will see some examples on how to use it.
