How to display the radius in MKCircle on Map in meters

I need to draw a circle of a radius 1.23 metre on MkMapView using MKCircle. How would i show that on the map. I used the following , 

  r = 1.23;// in metres.
  circle = [MKCircle circleWithCenterCoordinate:location radius:r];

But when i draw it on the map it looks like more than 1km on the MKMapView. Could someone please tell me how i could represent a circle of radius 1.23 metre on the map??

This is mainly to show the accuracy of the location, so the radius indicates the accuracy of the location.

MKCircle class definition says

radius

   The radius of the circle, measured in meters from the center point.

So your code should work fine.

In the viewForOverlay delegate method, try setting the lineWidth of the MKCircleView to 1.

I think the default width of 0 results in the "road width".
