The surface area of a cylinder is given as:
[tex]A=2\pi r^2+2\pi rh[/tex]where r is the radius and h is the height of the cylinder.
Plugging the values we have:
[tex]\begin{gathered} A=2\pi(14)^2+2\pi(14)(18) \\ A=392\pi+504\pi \\ A=896\pi \\ A\approx2815 \end{gathered}[/tex]Therefore the surface area of the cylinder is 2815 squared feet.
