Lesson Objective

In this lesson, we will learn about the volume
of a cone.

About This Lesson

In this lesson, we will:
**study tips** and **math video**
below will explain more.

- Learn about the formula for the volume of a cone and see how it is related to the volume of a cylinder.
- Look at an example on using the formula to calculate the cone's volume
- Look at another example on using the formula to calculate the base radius of a cone

Tip #1

In the previous lesson, we learn that the volume of a cylinder is **π****r**^{2}**h**.
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:

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

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

Hence, for a cone with height

where
