Question 1005163: 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 above the horizontal diameter is the car when the angle swept out has a measure of 2.9 radians?
Please answer and explain, thanks.

You can put this solution on YOUR website!
By definition, +pi+ radians is a point
180 degrees from the 3 o'clock position
+pi+-+2.9+ is the angle in radians
between the 9 o'clock position and
+2.9+ radians
+pi+-+2.9+=+.2416+ radians
+sin%28+.246+%29%2A2.9+=+.23925
----------------------
The car is .239 miles above the horizontal
This is the sin of the angle in radians times
the radius in miles
