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:
[tex]LA=2\pi rh[/tex]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:
[tex]\begin{gathered} LA=2\pi rh \\ LA=2\pi(4.75)(6.2) \\ LA=185.04 \end{gathered}[/tex]Pedro's mother needs 185.04 square inches of special paper
