If the minute hand of a big clock is 1.12m long, find the rate at which its tip is moving in centimeters per minute.

From the definition of Angular Speed:
the second hand travels a whole revolution of 360 degrees which has its equivalent as 2π. So, the equation will be
(1.12in)(2π/60min)=0.117in/min
Hope I helped you in solving. Best Regards
