title: Is it possible in Google Map Drawing a circle and check which coordinates falls on the circle?
body: <p>I have a big map in my site and I have implemented enabling drawing of shapes (like circle, rectangles) on it by the Google Maps API v3. </p>
  
  <p>I have a set of locations (consisting of coordinates). Is there a way that I can check which of the coordinated falls on the shape (say circle) user have drawn on the map?</p>
  
  <p>I have checked several questions here and searched on Google but couldn't find a specific way of doing it.</p>
  
  <p>Thanks.</p>
