Answer:

326.56 square feet

Step-by-step explanation:

Surface area of a cylinder = 2πrh + 2πr²

Radius = Diameter/2

= 8 ft/2

= 4 ft

Height = 9 ft

Surface area of a cylinder = 2πrh + 2πr²

= (2 * 3.14 * 4 * 9) + (2 * 3.14 * 4²)

= 226.08 + 100.48

= 326.56 square feet

Surface area of a cylinder = 326.56 square feet
