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. 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? you must show all of your work.

Part 1: There are 2π radians in a circle, so that is the angle the minute hand travels in 60 minutes. In 25 minutes (from 1:25 to 1:50), the minute hand travels
  (25/60)*2π = (5/6)π radians

Part 2:The distance the tip of the minute hand travels is this angle multiplied by the raidus of the hand, 4 in.
  (4 in)(5/6)π = 10π/3 in ≈ 10.47 in
