Assume I have a point at the following location:

Latitude: 47°36'N Longitude: 122°19'W

Around the above point, I draw a 35Km radius. I have another point now or several and I want to see if they fall within the 35Km radius? How can I do this? Is it possible with Linq given the coordinates (lat, long) of both points?
