Answer:
[tex]2080\pi \text{ square ft}[/tex]
Step-by-step explanation:
Since, the surface area of a cylinder is,
[tex]A=2\pi r( r+h)[/tex]
Where, r is radius,
h is the height,
Here,
The diameter of the cylinder = 40 ft,
So, the radius of the cylinder, r = [tex]\frac{40}{2}=20\text{ ft}[/tex]
And, h = 32 ft
Thus, the surface area of the cylinder is,
[tex]A=2\pi (20)(20+32)[/tex]
[tex]=40\pi (52)[/tex]
[tex]=2080\pi \text{ square ft}[/tex]
