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? You must show all of your work.

    well, there are 360 degrees in a circle, and 60 minutes in one hour, so how many degrees do you think are in one minute?

    @dan915 is that 2pi rad?

    rad is short for radius it means there are 2*pi radius units in a circle thats why the circle circumference is also 2pi*r

    3:35 to 3:55=20 minutes = 1/3 *360 degrees = 120 degrees 180 degrees = pi radians so 120 degrees = (2/3) pi radians. 2. 4" x (2/3)pi = (8/3)pi inches
