The formula for arc length is s=r*angle theta where s is the arc length, r is the radius, and angle theta is central angle formed by the arc in radians.
In this case, the angle would be s/r or 4.2/4 which is 1.05 radians. We have to convert this into degrees and so you would multiply 1.05 by (180/pi) which results in approximately 60 degrees. Remember, if you want to convert radians into degrees, the conversion factor is 180/pi and for degrees into radians, it is pi/180.
The answer TO your question is the sequence B
3/10 in
<span>1 in =(1/12)ft </span>
<span>1 ft =(1/5280) mi </span>
<span>3/10 in=3/10*(1/12)*(1/5280) mi </span>
