Help I need the answer

18.9 ft²

Step-by-step explanation:

Surface area of this cylinder = area of the bottom and top circles + area of the curved surface.

Area of the two circles = 2πr² , where r is the radius.

Area of the curved surface = 2πrh , where r is the radius and h is the height.

Radius = × diameter

Area of the two circles = 2 × π × ()² = 6.3 ft² (answer rounded up to nearest tenth)

Area of the curved surface = π × diameter × h = π × 2ft × 2ft = 12.6 ft² (answer rounded up to nearest tenth)

The surface area of the cylinder = 6.3 ft² + 12.6 ft² = 18.9 ft²
