Full solution stays hidden until you ask for it.
1. Identify radius, angle, time, or arc length.
2. Use s=r theta and angular speed equals theta/time.
3. Attach appropriate linear or angular units.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Mixing degrees with radians without conversion.
