Calculating distance...

Given the circumference and diameter of a planet (in this case say earth)
in miles (or kilometers) what formula could be used to calculate the
distance
between two known geographic coordinates? Assume the planet is a perfect
sphere and that points are given to the minute. An example: Given the
diameter of planet x, 12500 miles, what is the distance bewteen the points
42 deg 60 min N by 78 deg 40 min W and 38 deg 60 min by 65 deg 20 min.
Assume
planet x is a shere and an arbitrary equator and meridian are drawn.
Anybody have any ideas? Thanks,
Peter
