let each of the straights be x m
then the perimeter is
2x + 2half-circles
= 2x + circumference of 1 circle
2x + 2π(35) = 400
solve for x
There is a diagram of a running track. The track is made up of two straights and two semicircles. The radius of each semicircle is 35 meters. The length of the outer perimeter of the entire running track is 400 meters. Find the length of one of the straight sections of the track. Approximate ∏ as 3.14. Round your answer to the nearest tenth.
