Question
Laura is skiing on a circular ski trail that has a radius of 1.4 km, and Laura starts at the 3-o'clock position. Imagine an angle with a vertex at the
center of the ski trail.
a. If the angle measures 1.6 radians, then Laura is cos(1.6) radius lengths to the right and 1.004
the ski trail. Therefore, she is 1.399
]* radius lengths above the center of
