Answer:

$A=376.99\ units^2$

Explanation:

By definition, the surface area of a cylinder is given by the following formula:

$A = 2\pi r h + 2\pi r ^ 2$

Where r is the radius and h is the height.

In this case, we have to:

$r = 4\\\\h = 11$

then the surface area is:

$A = 2\pi(4)(11) + 2\pi(4) ^ 2$

$A=120\pi$

$A=376.99\ units^2$
