Angle moved by the hand in moving from midnight to 8 am =
= 2 π * 8 /12 = 4π/3 radians
The length of the circular curve that the top of the hand will move =
= 12 feet * 4 π /3 radians = 16 π feet
= 2 π * 8 /12 = 4π/3 radians
The length of the circular curve that the top of the hand will move =
= 12 feet * 4 π /3 radians = 16 π feet
