Answer:
572π ft² ≈ 1797 ft²
Step-by-step explanation:
You want the surface area of a cylinder with radius 11 feet and height 15 feet.
Area formula
The formula for the area of a cylinder is ...
A = 2πr(r +h) . . . . . . . radius r, height h
Application
For the given radius and height, the area is ...
A = 2π(11 ft)(11 +15 ft) = 572π ft² ≈ 1797 ft²
The area of the cylinder is about 1797 square feet.
