Question

How many radians will the hour hand on a clock rotate in 36 hours?

Answer 1

On a clock one rotation around the clock for 12 hours is 2pi, since the clock rotates for 36 hours that means that the clock rotates around the clock 3 times since 36/12=3. So 2pi*3= 6pi. Therefore the hour hand will rotate 6pi radians in 36 hours
