Answer:

$SA=703.36\ ft^2$

Explanation:

The picture of the question in the attached figure

we know that

The surface area of a cylinder is given by the formula

$SA=2(\pi r^(2))+2\pi rh$

simplify

$SA=2\pi r(r+h)$

we have

$h=9\ ft\\r=7\ ft$

assume

$\pi=3.14$

substitute

$SA=2(3.14)(7)(7+9)=703.36\ ft^2$
