Michael is sitting on a Ferris wheel. He is exactly 21 feet from the center and is at the 3 o'clock position when the Ferris wheel begins moving. The bottom of the Ferris wheel is 8 feet above the ground. The Ferris wheel broke down within the first revolution of the ride when Michael was at the point (-6.454, -19.984). a. What is the measure of the angle (in radians) that has a vertex (0,0)and rays through the point (21,0) and (-6.454, -19.984)?

θ= radians   

b. How many feet did Michael travel along the arc before stopping?
