Answer:

Explanation:

circumference of cylinder = πd = 5π in

lateral area of cylinder = 5π×9 = 45π in²

Each colored face has a matching face on the other side of the figure.

green areas = 2(17×15) = 510 in²

blue areas = 2(12×17) = 408 in²

gray areas = 2(5×6) = 60 in²

yellow areas = 2(5×12) = 120 in²

red areas = 2(12×15) = 360 in²

total surface area = 45π + 510 + 408 + 60 + 120 + 360 ≅ 1,599.37 in²
