Valerie is skiing along a circular ski trail with a radius 2.5 km long. she starts at the 3 -o'clock position (the easternmost position on the trail) and travels in the counterclockwise direction. valerie stops skiing when she is 1.134 km east and 2.228 km north of the ski trail's center. (we recommend drawing a picture of this situation.) imagine an angle with its vertex at the ski trail's center that subtends the path valerie skis. how many radians has the angle swept out since valerie started skiing? correct radians how many km has valerie traveled since she started skiing?
