Question 769958
Minute Hand: 12 cm
Hour Hand: (2/3)*12=8 cm


Know that in 12 hours, the minute hand points around the clock face 12 times and the hour hand points around 1 time.  


The circumference traveled for the minute hand will be {{{pi*12^2}}}, so then the amount of point traveling in 12 hours will be {{{12*pi*12^2}}}.


The circumference traveled for the hour hand is {{{pi*8^2}}}.  


MINUTE HAND TRAVELS:  {{{highlight(12*pi*12^2)}}}
HOUR HAND TRAVELS:  {{{highlight(pi*8^2)}}}
