Question 441324
The radius of the earth is about 3959 miles. 

How far apart are two points on the surface of the earth that make a central angle of 73 degrees?
---------------------
The max distance between them is the circumference times 73/360
d = 2*pi*r*73/360
d = 2*pi*3959*73/360
d =~ 5044 miles
