Hi list, 
Here's how i solved the problem:

formats = {
  'in': {
  wkt: new OpenLayers.Format.WKT(in_options)
  'out': {
  wkt: new OpenLayers.Format.WKT(out_options)

var limits=feature.geometry.getBounds();
var center=limits.getCenterLonLat();
var center2=new OpenLayers.Geometry.Point(center.lon, center.lat);
var center_feat=new OpenLayers.Feature.Vector(center2); 
var str = formats['out']['wkt'].write(center_feat, '1');
str = str.replace(/,/g, ', ');

/*coordinates must be inverted: switch lat and long. This is the center of
the geometry*/
var x=str.split("(");
var y=x[1].split(")");
var w=y[0].split(" ");
var str_new="POINT("+w[1]+" "+w[0]+")";

/* This is the radius of the circle*/
var radius=limits.getWidth()/2;
