Problema Solution

A runner jogged 0.1 mile in one lap around a circular track in a field house. What is the greatest distance measured straight across the track in feet?

Answer provided by our tutors

we are given the perimeter of a circle:


P = 0.1 mi = 0.1*5280 ft = 528 ft


the greatest distance measured straight across the track is the diameter d of this circle:


P = d*pi


d*pi = 528


pi = 3.14


d = 528/pi


d = 528/3.14


d = 168.15 ft


the greatest distance measured straight across the track is 168.15 feet.
