The radius of the circle with a central angle of http://webwork.mathstat.concordia.ca...219fe87b11.png that intercepts an arc with length 9 miles is miles.

I came up with 2.02 miles

or 12.7 miles both seem wrong

but then if the formula is S=r(theta) and I would get 9=r(255) r=9/255 r=.035?

I am just not sure what to do?
