Answer
$66\pi$ square feet
Work Step by Step
The surface area $(S.A.)$ of a cylinder is given by the formula:
$S.A.=2\pi{rh}+2\pi{r^2}$
where
$r$=radius
$h$=height
The given cylinder has:
$r=3$ ft
$h=8$ ft
Using the formula above gives:
$S.A.=2\pi(3)(8)+2\pi(3^2)
\\S.A.=48\pi + 18\pi
\\S.A.=66\pi$
Therefore, the surface area of the cylinder is $66\pi$ square feet.
