The surface area of a cylinder is given by the formula: 2πr(r + h), where r is the radius and h is the height.

Plugging in the values provided:
r = 7 yards
h = 8 yards

Surface area = 2 * 3.14 * 7(7 + 8)
Surface area = 2 * 3.14 * 7(15)
Surface area = 2 * 3.14 * 105
Surface area = 6.28 * 105
Surface area = 659.4 square yards

Therefore, the correct answer is 659.4 square yards. Out of the options provided, the closest answer is 577.76 square yards.
