C Correct answer
Explanation

Total surface area of a cylinder = 2 * pi * r * (r + h). Here, r = 5, h = 12. Area = 2 * pi * 5 * (5 + 12) = 10 * pi * 17 = 170pi.

AI explanation

The total surface area of a cylinder is found by the formula 2 times pi times r times (h plus r). Substituting the radius of 5 inches and height of 12 inches gives 2 times pi times 5 times 17. Multiplying these values results in 170 times pi square inches.
