The document provides examples of problems involving angles, radians, and the unit circle. It asks how many degrees a bicycle wheel has turned given its diameter and distance traveled by a point on the rim. It also asks how many radians the wheel has turned and how many radians are between the minute and hour hands of a clock at 4:00. The document asks for a positive coterminal angle for an expression and the area of a sector of a circle given the central angle and radius.
