Lets get started :)
The area formula of a cylinder is:
Area = [tex]2(radius)^2+2 \pi (radius)(height)[/tex]
We are given:
The radius: 6 units
The height: 15 units
Apply the formula!
A = [tex]2 \pi (6)^2+2(6)(15)[/tex]
= [tex]72 \pi + 180 \pi [/tex]
= [tex]252 \pi [/tex] units²
Your answer will be option D
