Solving Haversine Formula For Longitude And Latitude

Hi all, I would like to find all the Longitudes and Latitudes of all the places that are within a 10 mile radius from a point whose Longitude and Latitude is known.

I have looked at the Haversine Formula below but it doesn't help.

R = 3961 mi
dlon = lon2 - lon1
dlat = lat2 - lat1
a = (sin(dlat/2))^2 + cos(lat1) * cos(lat2) * (sin(dlon/2))^2
c = 2 * atan2( sqrt(a), sqrt(1-a) )
d = R * c (where R is the radius of the Earth)

The reason it doesn't help is because I am left with 2 unknowns instead of just 1. The unknowns are lon2 and lat2 which I was hoping to determine by solving for either one of them.

Please help me solve for all the lon2 and all the lat2. Thanks in advance for your help.
