Answer:

96π yd² ≈ 301.6 yd²

Explanation:

The total surface area of a cylinder, including flat circular top and bottom and curved lateral surface, is given by the formula ...

S = 2πr² + 2πrh . . . . . where r is the radius and h is the height

For a radius of 3 yards and a height of 13 yards, the area is ...

S = 2π(3 yd)² + 2π(3 yd)(13 yd)

S = 18π yd² + 78π yd²

S = 96π yd² ≈ 301.6 yd²

The total surface area is about 301.6 square yards.
