Answer 1

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

The formula for the area of a circle is A = πr^2, where A is the area and r is the radius.

The area of the two circular bases is 2(π(5)^2) = 2(3.14(25)) = 2(78.5) = 157 square inches.

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

The lateral surface area is 2(3.14)(5)(10) = 314 square inches.

Therefore, the total surface area of the cylinder is 157 + 314 = 471 square inches.

The correct answer is 471 square inches.
