At a school carnival, the diameter of the mat of a trampoline is 10 feet and the diameter of its metal frame is 12 feet. What is the length, in feet, of the metal frame that surrounds the trampoline? Use 3.14 for π and round your answer to the nearest tenth.
15.7 feet
18.9 feet
31.4 feet
37.7 feet



Answer :

eternal3fear
circumference = pi * diameter
circumference of metal frame = pi * (diameter of metal frame)

(diameter of metal frame) = 12

Circumference of Metal Frame = 3.14 * 12 = 37.68

therefore D: 37.7 feet would be your answer
