Answer:

Explanation:

The cylinder contains three areas, the top circle, the bottom circle, and the middle. The surface area of it is the sum of the three;


As = \pi r^(2) + \pi r^(2) + 2\pi r (h) \\

or


As = 2\pi r^(2) + 2\pi r (h)

where h is the height,

104
\pi =
2 \pi (4)^(2) + 2\pi (4)(h)

h = 9m
