This is a question similar to what will be on my test tomorrow. I'd really appreciate the help on how to figure this out.

The answer is 330 Pi or 1,036.7 miles.

**Reiny**, Wednesday, April 29, 2009 at 10:56pmdraw a 'great circle'

the two towns form a sector with an angle

of 15º (53.6-38.6 = 15)

15º = pi/12 radians

you want the arclength of that sector

arclength = radius x angle

= 3960(pi/12) = 330pi
