To find the surface area of a cylinder, we need to calculate the area of the two circular bases and the lateral surface area.

The area of a circular base is given by the formula A = πr^2, where r is the radius.

For our cylinder, the radius is 5 inches, so the area of each circular base is A = 3.14 * (5^2) = 3.14 * 25 = 78.5 square inches.

The lateral surface area of a cylinder is given by the formula A = 2πrh, where r is the radius and h is the height.

For our cylinder, the radius is 5 inches and the height is 10 inches, so the lateral surface area is A = 2 * 3.14 * 5 * 10 = 314 square inches.

Summing up the areas of the circular bases and the lateral surface area, we get the total surface area of the cylinder:

Total surface area = 2 * 78.5 + 314 = 157 + 314 = 471 square inches.

So, the correct answer is: 471 square inches.
