Question

Pedro's mother was labeling items in the kitchen and she decided to decorate one of her cylinder storage containers with special paper.She asked for Pedro's help, the radius is 4.75 inches and the height of 6.2 inches.How much does she need?(You are not to include the top or bottom)

Answer 1

Pedro's mother is decorating the lateral surface, not the top and bottom.

Thus, we need to find the lateral surface area of the cylinder.

The lateral surface area formula is:

`LA=2\pi rh`

Where

LA is lateral surface area

r is the radius

h is the height

Given,

r = 4.75 inches

h = 6.2 inches

Let's calculate the amount of special paper she needs:

`\begin{gathered} LA=2\pi rh \\ LA=2\pi(4.75)(6.2) \\ LA=185.04 \end{gathered}`

Pedro's mother needs 185.04 square inches of special paper
