Answer:
![6524.51 ft^2](https://tex.z-dn.net/?f=6524.51%20ft%5E2)
Step-by-step explanation:
The surface area of a cylinder is given as;
![SA = 2\pi rh + 2\pi r^2](https://tex.z-dn.net/?f=SA%20%3D%202%5Cpi%20rh%20%2B%202%5Cpi%20r%5E2)
where r = radius
h = height
The cylinder has a height of 32 feet and a diameter of 40 feet. This means that the radius is:
40 / 2 = 20 feet
The surface area is therefore:
![SA = (2*\pi* 20 * 32) + (2*\pi *20^2)\\\\SA = 4021.24 + 2513.27\\\\SA = 6524.51 ft^2](https://tex.z-dn.net/?f=SA%20%3D%20%282%2A%5Cpi%2A%2020%20%2A%2032%29%20%2B%20%282%2A%5Cpi%20%2A20%5E2%29%5C%5C%5C%5CSA%20%3D%204021.24%20%2B%202513.27%5C%5C%5C%5CSA%20%3D%206524.51%20ft%5E2)
The surface area of the cylinder is
