Michelle is skiing along a circular ski trail that has a radius 2.9 km long. She starts at the 3 -o'clock position (the easternmost point on the trail) and travels in the counterclockwise direction. Michelle stops skiing when she is 1.051 km east and 2.703 km north of the ski trail's center. Imagine an angle with its vertex at the ski trail's center that subtends Michelle's path. What is the angle's measure in radians? radians Hint: You might use one of the following functions: cos 1 , sin 1 , or tan 1 . How far did Michelle travel in km? km Hint: Recall that = s r (or s = r ) if an angle has a measure of radians and subtends an arc s units long along a circle with a radius r units long
