    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

    length = 2 + pi * r where r = radius of the frame

    well you could use the diameter which is the length = circumference = pi * d = 3.14 * 12
