title: Showing google map marker in specified circle/area only
body: <p>I want to show the markers in the specified area only! For example, I want to draw the circle with radius suppose 3 or any and center (any LatLng). Then, I need to display the marker only in the regions of that circle.
  How can I achieve that? Is it possible?</p>
  
  <p>Update: Solution to my question</p>
  
  <pre><code>function isMarkerInArea(circle, marker)
  {
     return (circle.getBounds().contains(marker.getPosition()));
  };
  </code></pre>
  
  <p>Description: </p>
  
  <ul>
  <li>circle.getBounds() returns the latLng bounds of circle</li>
  <li>marker.getPosition() returns the latLng of the marker</li>
  <li>and finally circle.getBounds().contains(marker.getPosition()) , returns the boolean value if the marker is within the circle all not.</li>
  </ul>
  
  <p>Finally, set the visibility of the marker as per the boolean returned!</p>
