**Reiny**, Tuesday, May 15, 2012 at 10:23pmthe miles of reception would be the length of the chord as the highway cuts through the circle of reception.

I see a right-angled triangle, with a hypotenuse of 6.1 (radius of the circle) , a side of 3 (highway is 3 miles from station) and a third side of x

x^2 + 3^2 = 6.1^2

x = √28.21

= 5.311

so the length of the chord (miles of reception) is 2(5.311) or 10.62 miles.
