What is the surface area of the cylinder?

Surface area of the cylinder is 66π ft²

Step-by-step 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
