To find the surface area of a cylinder, we need to find the sum of the areas of the two bases and the lateral surface area.
The formula for the surface area of a cylinder is:
Surface Area = 2πr^2 + 2πrh
Given that the radius (r) is 5 inches and the height (h) is 10 inches, we can plug in these values and use the approximation of π as 3.14.
Surface Area = 2(3.14)(5^2) + 2(3.14)(5)(10)
Surface Area = 2(3.14)(25) + 2(3.14)(5)(10)
Surface Area = 157 + 314
Surface Area = 471 square inches
Therefore, the correct answer is:
471 square inches

The formula for the surface area of a cylinder is:
Surface Area = 2πr^2 + 2πrh
Given that the radius (r) is 7 yards and the height (h) is 8 yards, we can plug in these values and use the approximation of π as 3.14.
Surface Area = 2(3.14)(7^2) + 2(3.14)(7)(8)
Surface Area = 2(3.14)(49) + 2(3.14)(7)(8)
Surface Area = 307.86 + 351.68
Surface Area = 659.54 square yards
Therefore, the correct answer is:
659.54 square yards.

Given that the radius (r) is 2 yards and the height (h) is 3 yards, we can plug in these values and use the approximation of π as 3.14.
Surface Area = 2(3.14)(2^2) + 2(3.14)(2)(3)
Surface Area = 2(3.14)(4) + 2(3.14)(2)(3)
Surface Area = 25.12 + 37.68
Surface Area = 62.8 square yards
Therefore, the correct answer is:
62.8 square yards.
