I'm guessing you draw a 12 degree angle from the center in the 4th quadrant of a graph. Thus, you get a triangle but what would be the next step?

Well, you have some idea.
I'm thinking that if the radius is 3963, then the circumference is 3963 * 2 * pi, and then since there are 360 degrees in a circle, I'm thinking divide circumference by 360, giving you miles-per-degree. Then, finish up by.... figuring from there.
