A toy racecar races along a circular race track that has a radius of 24 meters. The racecar starts at the 3-o'clock position of the track and travels in the CCW direction. Suppose the racecar has traveled 56 meters along the race track.

How many radians has the racecar swept out?
 radians   

What is the racecar's distance to the right of the center of the race track (in meters)?
 meters   

What is the racecar's distance above the center of the race track (in meters)?
 meters   

Let d represent the racecar's varying distance traveled (in meters) along the circular race track.

Write an expression (in terms of d) to represent the racecar's distance to the right of the center of the race track (in meters).
 

Write an expression (in terms of d) to represent the racecar's distance above the center of the race track (in meters).
