Use the net to find the surface area of the cylinder

Step-by-step explanation:

To find the surface area of the cylinder you must apply the following proccedure:

- Calculate the surface area of the circles. They are equal, then you can multiply the surface area of a circle by 2:

Where r is the radius.

- Calculate the surface area of the rectangle:

Where l is the lenght and w is the width.

(The length is the circumference of the circle)

Then:

- Add the areas obtained.

The result is:

part 1 answer = 8

part 2 answer = 72

step-by-step explanation:

part 1 explanation = add all of the numbers, then divide by how many numbers you have. so, 200/25 = 8.

part 2 explanation = not gonna lie, this is hard to explain, so just google how to do it.
