The surface area of a cylinder can be calculated using the formula:

Surface Area = 2πrh + 2πr^2

Given:
Height (h) = 8 yards
Radius (r) = Width/2 = 7/2 = 3.5 yards

Substituting the given values into the formula:

Surface Area = 2 * 3.14 * 3.5 * 8 + 2 * 3.14 * 3.5^2
Surface Area = 175.84 + 153.86
Surface Area = 329.7 square yards

Therefore, the surface area of the cylinder is approximately 329.7 square yards.
The correct answer is option C. 329.7 square yards.

The surface area of a cylinder can be calculated using the formula:

Surface Area = 2πrh + 2πr^2

Given:
Height (h) = 3 yards
Radius (r) = Width/2 = 2/2 = 1 yard

Substituting the given values into the formula:

Surface Area = 2 * 3.14 * 1 * 3 + 2 * 3.14 * 1^2
Surface Area = 18.84 + 6.28
Surface Area = 25.12

Therefore, the surface area of the cylinder is approximately 25.12 square yards.
The correct answer is option D. 25.12 square yards.

The surface area of a cylinder can be calculated using the formula:

Surface Area = 2πrh + 2πr^2

Given:
Diameter = 6 inches
Radius (r) = Diameter/2 = 6/2 = 3 inches
Height (h) = 4 inches

Substituting the given values into the formula:

Surface Area = 2 * 3.14 * 3 * 4 + 2 * 3.14 * 3^2
Surface Area = 75.36 + 56.52
Surface Area = 131.88

Therefore, the label on the outside of the can will require approximately 131.88 square inches of paper.
The correct answer is option D. 131.88 square inches.
