Finding the volume of a cylinder

The video tutorial explains how to calculate the volume of a cylinder. It begins with an introduction to the concept of volume, using a cylinder as an example. The instructor uses a can of food to illustrate the idea of a cylinder and explains the difference between volume and surface area. The tutorial then covers how to calculate the area of a circle, which is a crucial step in finding the volume. The instructor explains the formula for the volume of a cylinder, pi r squared times height, and clarifies the role of height in the calculation. The video concludes with a step-by-step demonstration of calculating the volume of a cylinder.

What is the primary difference between volume and surface area?

• Volume measures the length of an object, while surface area measures the width.

• Volume measures the weight of an object, while surface area measures the height.

• Volume measures the space inside an object, while surface area measures the space on the surface.

• Volume measures the color of an object, while surface area measures the texture.

Which formula is used to calculate the area of a circle?

• Area = 2πr

• Area = πr^2

• Area = πd

• Area = 2πr^2

Why is the height important when calculating the volume of a cylinder?

• It is used to calculate the diameter.

• It is multiplied by the base area to find the volume.

• It is used to calculate the surface area.

• It determines the color of the cylinder.

What is the height of the cylinder in the example provided?

• 6

• 9

• 8

• 15

How do you find the volume of a cylinder?

• Multiply the diameter by the height.

• Multiply the circumference by the height.

• Multiply the area of the base by the height.

• Multiply the radius by the height.
