The length of the band is three times the length of the 120 degrees arc of the circle of the radius of 3 cm 

PLUS  3 times the distance between the centers of the rods.


In other words,  


    The length of the band = {{{3*(1/3)*2pi*3}}} + 3*(2*3) = {{{2pi*3}}} + 3*6 = 2*3.14*3 + 3*6 = 36.84 cm  (approximately).   <U>ANSWER</U>
