You can put this solution on YOUR website! Pittsburgh, Pennsylvania, and Buffalo, New York, lie approximately on the same meridian. Pittsburgh has a latitude of 40.5°N, and Buffalo has a latitude of 42.9°N. Find the distance between these two cities. (The radius of the earth is 3960 mi. Round your answer to the nearest mile.)
========
Find the circumference of the earth:: C = pi*(2*3960) miles
----
Find the angle between the cities:: 43.9-40.5 = 3.4 degrees
------
Equation::
Ans (3.4/360)(pi*2*3960) miles = 235 miles
