Answer:

Explanation:

This problem is on the mensuration of flat shapes, a circular shape.

the problem also requires that we find the perimeter of the circular track

the expression for the perimeter of a circle is given as

$C= 2\pi r$

Given

diameter of the circular track = 75 meters

radius of circular track = d/2 = 75/2= 37.5 meters

Substituting our data into the expression for perimeter we have

$C= 2*3.142 *37.5\\\\C= 235.65$

Approximately the length is 235 meters.
