Volume and Area of Cylinders

This video tutorial covers Math 8 Unit 5 Lesson 13 on calculating the volume of a cylinder. It begins with an introduction to the lesson, followed by an explanation of cylinder dimensions, including height and radius. The tutorial then demonstrates how to calculate the area of the base using Pi and how to use this to find the volume of the cylinder. It also includes practice problems for students to apply their learning, with instructions on how to approximate the volume using 3.14 for Pi.

What is the main topic of Math 8 Unit 5 Lesson 13?

• The volume of a cylinder

• 12 Pi

• 4 Pi

• 16 Pi

• 8 Pi

What is the formula for the volume of a cylinder?

• Base area divided by height

• Base area plus height

• Base area minus height

• Base area times height

How do you convert the volume of a cylinder from terms of Pi to a decimal approximation?

• Multiply by 2
