Learning to find the suface area of a cylinder

The video tutorial explains how to calculate the lateral surface area of a cylinder. It begins by discussing the area of the base, which is a circle, and how to multiply it by two to account for both the top and bottom. The tutorial then covers the area wrapped around the cylinder, described as a rectangle with a height and a length equal to the circumference of the circle. The circumference is calculated using the diameter, which is twice the radius. The final calculation involves using these measurements to find the total surface area, resulting in a value of 1005.31.

What is the formula used to find the area of the base of a cylinder?

• 2π times the radius

• π times the height

• π times the radius squared

• π times the diameter

How do you determine the length of the rectangle that wraps around the cylinder?

• By doubling the radius of the base

• By using the circumference of the base

• By calculating the diameter of the base

• By measuring the height of the cylinder

What is the relationship between the radius and the diameter of a circle?

• The diameter is half the radius

• The diameter is twice the radius

• The diameter is equal to the radius

• The diameter is the square of the radius

Which of the following is part of the formula to calculate the total surface area of a cylinder?

• 2 times π times the radius squared

• 2 times π times the height

• π times the height squared

• π times the diameter squared

What is the final calculated total surface area of the cylinder, rounded to the nearest hundredth?

• 980.25

• 1100.50

• 1005.31

• 1020.45
