Answer:

596.9 cm^2

Step-by-step explanation:

The surface area of a cylinder is $SA=2\pi rh+2\pi r^2$ where $r$ is the radius of the base of the cylinder and $h$ is the height of the cylinder.

So, the surface area of the cylinder is:

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

$SA=2\pi (5)(14)+2\pi (5)^2$

$SA=2\pi(70)+2\pi(25)$

$SA=2\pi(70+25)$

$SA=2\pi(95)$

$SA=190\pi$

$SA\approx596.9$
