Freddie is at chess practice waiting on his opponent's next move. He notices that the 4inchlong 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?

Best ResponseYou've already chosen the best response.0rad is short for radius it means there are 2*pi radius units in a circle thats why the circle circumference is also 2pi*r

Best ResponseYou've already chosen the best response.03:35 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
