Freddie is at chess practice waiting on his opponent's next move. He notices that the 4-inch-long minute hand is rotating around the clock and marking off time like degrees on a unit circle.
Part 1: How many radians does the minute hand move from 3:35 to 3:55? (Hint: Find the number of degrees per minute first.)
Part 2: How far does the tip of the minute hand travel during that time?
Part 3: How many radians on the unit circle would the minute hand travel from 0° if it were to move 3π inches?
Part 4: What is the coordinate points associated with this radian measure?

First step is to find how many degrees there are per minute. 60 minutes to 360 degrees. So how many degrees per minute?
6 degrees per minute
Right. And we're trying to figure out how many degrees there are for 20 minutes. \[\large \sf 20 \times 6 =120\] so we're solving for 120 degrees. Do you know what 120 degrees looks like in radian form?
