Best ResponseYou've already chosen the best response.2The track is made up of 2 line segments each 130 m long. Then the track also is made up of 2 semicircles. Two semicircles combine to form one circle. P = 130 m + 130 m + circumference of circle. To find the circumference of the circle use the formula, \(C = \pi d\) You are given d, the diameter as 56 m.

Best ResponseYou've already chosen the best response.2Yes. pi * diameter is the full circle's circumference. Then you add that to 130 + 130.
