Solution

Hint:
Step 1: The surface area of the cylinder $= 2 {πr}^{2} + 2 πrh$
Step 2: Surface area $= 2 \times 3.14 \times 4 \times 4 + 2 \times 3.14 \times 4 \times 50$
Step 3: Surface area $= 100.48 + 1256$
Surface area $= 1, 356.48 s q . f t$
Final answer: The surface area is $1, 356.48 s q . f t$
