Hello,
I am facing a big issue while using the ArcGIS JS API 2.0 when drawing circle zone on map according to a given center point and radius.
I received From My database centerPoint in LAT/LON and Radius in meters and need to draw circle zone accordingly. Unfortunately I found that the only way to draw circle without toolbar is by calling my geometryService.buffer function which returns a buffer polygon.
When I draw the buffer on the map, it shows a polygon shaped like a circle - But that's unacceptable by our customers.
What should I do?
I need your assistance urgently. thanks for any help.
Regards,
Jordan.

var polygon = new esri.geometry.Polygon();
var points = [];
for ( var i = 0; i <= 360; i += 10) {
var radian = i * (Math.PI / 180.0);
var x = pt.x + radius * Math.cos(radian);
var y = pt.y + radius * Math.sin(radian);
points.push(new esri.geometry.Point(x, y));
}
polygon.addRing(points);
polygon.spatialReference = map.spatialReference;
return polygon;
}
