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.
