A and B are two places on longitude 10W. If their latitudes differ by 63 ,
find the distance of A from B.
~~~~~~~~~~~~~~~~~~~~
The points A and B lie in one great circle of the Earth, with the central angle between them of 63 degrees.
THEREFORE, the distance from A to B is = = 7037 kilometers (approximately).
In the formula, R = 6400 is the approximate radius of the Earth (in kilometers).
