Calculating the Volume of Cylinders

The video tutorial introduces the concept of volume, focusing on cylinders. It explains the formula for calculating the volume of a cylinder, which is volume equals pi times the radius squared times the height. The tutorial breaks down each component of the formula, including pi, radius, and height, and provides a step-by-step example of how to apply the formula to solve a problem. The video aims to help students understand the calculation of volume for cylindrical objects, using relatable examples like cans of dry shampoo or Pringles.

What is volume?

• The height of an object

• The amount of space inside an object

• The surface area of an object
