I need to know the radial distance from a residential address in one
city to a business address in another city.  Not the driving miles,
but the distance between the two as the crow flies.  The residence
address is 9818 Elder Avenue, Hanford, CA  93230 and the business
address is Fresno Coin Gallery, 4616 N. Blackstone Ave., Fresno, CA

Distance between 36:23:11N 119:38:07W and 36:48:06N 119:47:26W, as the crow flies:

    30 miles (48 km) (26 nautical miles)

Initial heading from 36:23:11N 119:38:07W to 36:48:06N 119:47:26W:
    north-northwest (343.3 degrees) 
Initial heading from 36:48:06N 119:47:26W to 36:23:11N 119:38:07W:
    south-southeast (163.2 degrees) 

36:23:11N 119:38:07W
9818 Elder Avenue, Hanford, CA  93230
    Location: 36:23:11N 119:38:07W

36:48:06N 119:47:26W
Fresno Coin Gallery, 4616 N. Blackstone Ave., Fresno, CA
    Location: 36:48:06N 119:47:26W

searched for crow flies distance
came up with this --> http://www.indo.com/cgi-bin/dist
this will calculate the distance based on geographical coordinates

found the geographical coordinates on terraserver using their address search.

should be accurate to about 100 feet
