Answer:
Surface area of the cylinder is 66π ft²
Explanation:
We have to find the surface area of the given cylinder with radius r = 3 ft. and height h = 8 ft.
From the formula of the surface area of the cylinder.
Surface area = 2(πrh + πr²)
= 2π ( 3 × 8 + 3²)
= 2π ( 24 + 9) = 2π (33)
= 66π ft²
Surface area of the cylinder is 66π ft²
