Copying on a circle

I have some object. I want to copy this object *count* times on a circle. Copies must be symmetric depending on their amount. I mean their placing on a circle. So now i have just this: for (int i = 0; i < count; i++) { objCone[i] = Instantiate (obj, new Vector3 (i*dist * xCor, yCor, 0), Quaternion.identity) as GameObject; }
