Question

Please help im so confused?

Answer 1

Lets get started :)

The area formula of a cylinder is:
Area = $2(radius)^2+2 \pi (radius)(height)$

We are given:
The radius: 6 units
The height: 15 units

Apply the formula!

A = $2 \pi (6)^2+2(6)(15)$
   = $72 \pi + 180 \pi$
   = $252 \pi$ units²

Your answer will be option D
