Is there a way to take an address and search a 200 mile perameter for a certain type of business like bakery?

I know on google maps you can put in an address and do search nearby but I'm looking to specify a perameter of 200 miles. For some reason I can not download google earth so I'm not sure if it allows this or if there are any other mapping systems online that do this. Thanks for your help!|||try using google to help you, and if all else fails use google maps or mapquest.com
