title: Finding intersecting areas in MySQL spatial db
body: <p>In a MySQL database, how do I find circular areas that fall entirely or partially within a certain distance from another point? There are plenty of examples to find points within a certain radius, but not circular areas that intersect that certain radius.</p>
  
  <p>I have a list of contractors that service certain areas (point and radius). Customers need to be able to find these contractors based on a distance from them.</p>
