Find the circumference of a circle with a radius of 10"

C = 62.83 inches
120 degrees is 1/3 of a circle
* 62.83 = 20.94 inches

1)
The wrench is the radius of the circle you form when you turn the wrench.
The circumference traced by the wrench is: Pi*2r = Pi*2(10) = 62.83
-.-.-.-.-.-
2)
the full circle is 360 degrees, we want 360/120 = 3 and 62.83/3 = 20.94 is the distance, in inches, measured at the tip of the handle, you traveled in 120 degrees.
