Question

What would the surface area be?

Answer 1

`2\pi r^2 + 2\pi r h`

Explanation:

The surface area of this cylinder can be found by thinking about this shape a little. You need to find the area of both the top and bottom of the cylinder, which you can find the formula for the area of a circle. To find the area of the wrapping on the sides, you can envision taking the cylinder and unwrapping it to form a rectangle. The area of the rectangle is the height of the cylinder multiplied by the circumference of the circle at the top. Therefore, the formula to find the surface area of this figure is
`2\pi r^2 + 2\pi r h`. Hope this helps!
