Question

A running track in the shape of an oval is shown. The ends of the track form semicircles.

A running track is shown. The left and right edges of the track are identical curves. The top and bottom edges of the track are straight lines. The track has width 56 m and length of one straight edge 130 m.
What is the perimeter of the inside of the track?

(π = 3.14)

260.00 m
347.92 m
372.00 m
435.84 m

Answer 1

something like this?

Answer 2

the inside of the track is made up of:

1. two straight horizontal sides (130 each, so 2*130)
2. two semicircles with diameter 56. two semicircles make up one whole circle in terms of perimeter, so take the perimeter of the semicircles combined to be pi * diameter. Like the problem says, use pi = 3.14.
3. add the results from step 1 and 2.
