Question 1148933
the radius is 3 cm.
The two radii where the band is tangent to a circle, are at an angle of 120 degrees.
There are 2*3=6 radii where the band is not touching a circle
There are 3*120 degrees or one full circle where the band reaches a circle
the radii are 3 cm, so that distance is 18 cm
The other distance is 6 pi, the circumference of one circle
The total distance is 18+6 pi or 36.85 cm or 37 cm.
