I draw many circles on the shape file, but I need to get a list of each radius and position.(I only see each circles' ID in the attributes now...)
You do not state which version of ArcGIS you are using (you should always do that). If you are using 10.2 then you can use the Add Geometry Attribute tool to at add the centroid XY coordinates.
As for the radius you could add a field and calculate it using:
radius = sqrt(Area/pi)
