Question

Celia is staring at the clock waiting for school to end so that she can go to track practice. She notices that the 4-inch-long minute hand is rotating around the clock and marking off time like degrees on a unit circle.

Answer 1

Part 1: How many radians does the minute hand move from 1:25 to 1:50? (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 5π inches?

Part 4: What is the coordinate point associated with this radian measure
