A running track in the shape of an oval is shown the end of the track form semicircles. What is the perimeter of the inside of the track 56 m 130 m
The perimeter of the inside of the track can be found by adding the circumference of the two semicircles plus the length of the straight part of the track.
The circumference of a circle is found using the formula C = π*d, where d is the diameter of the circle. Since we have semicircles with diameters of 56m and 130m, the circumference of the two semicircles would be:
C1 = π*56m = 176m
C2 = π*130m = 408.4m
The length of the straight part of the track is the width of the track, which is essentially the difference between the two diameters. We have: 130m - 56m = 74m
Therefore, the total perimeter of the inside of the track would be:
Perimeter = 176m + 408.4m + 74m = 658.4m
So, the perimeter of the inside of the track is 658.4 meters.
