Answer:
A. 622.04 ft²
Step-by-step explanation:
The lateral area of a cylinder is the area on the outside, meaning if you would cut open a cylinder longitudinally, and folded it open, the rectangle that remains is the lateral area of the cylinder.
The formula for the lateral area of a cylinder is:
[tex]A_{l} = 2\pi *r*h[/tex]
Where 2πr represents one side of the rectangle, and h represents the other.
[tex]A_{l} =2*\pi *11*9\\A_{l}=622.0353ft^{2}[/tex]
A ≈ 622.04 ft²
