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?

How many radians does the minute hand move from 1:25 to 1:50?

Calculations are done as follows:

360 ° /60 minutes = 6° per minute 
1:25 to 1:50 = 25 minutes

25 minutes x 6° per minute = 150°
150° (π/180) = 5π/6

Kabbed · Answer

where does (pi/180) come from

@Hero

Kabbed · Answer

to change a degree to a radian you use pi/180 which is called a formula I think

Hero · Answer

Well actually pi = 180 when converting from degrees to radians and vice versa.
