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