Question 1005667
A race-car starts at the 3 o'clock position and drives counterclockwise on a circular track with a radius 2.9 miles.

How many miles to the right of the center of the track is the car when the car has traveled 10.5 miles? 
----------------
Find the angle at the center.
angle A = arc/r = 10.5/2.9 radians
The horizontal distance (x value) = 2.9*cos(A)
=~ -2.57 miles
--> It's to the left of center.  The 1/2 way point is 2.9*pi =~ 9.11 miles
