$569.91\ ft^2$

Step-by-step explanation:

From the given picture, the radius of the base of the cylinder = 5.5 ft.

The height of the cylinder = 5 ft.+6 ft.=11 ft.

We know that the surface area of a cylinder is given by :-

$\text{Surface Area}=2\pi r (r+h)\\\\\Rightarrow\text{Surface Area}=2(3.14)(5.5)(5.5+11)\\\\\Rightarrow\text{Surface Area}=569.91\ ft^2$

Hence, the surface area of the given cylinder = $569.91\ ft^2$
