How to change the rotation of the circle spawn?

there is a cube and beside it to spawn things in the zone of a circle with a hole, but you need to change the rotation of this circle

    public class SpawnOre : MonoBehaviour {
      public GameObject prefabs;
          public float holeRadius = 1.0f;
          public float diskRadius = 2.5f;
          public Vector3 holeLocalPos = Vector3.zero;



// Use this for initialization
void Start () {
	InvokeRepeating("Spawner", 0.01f, 0.01f);
	
}

// Update is called once per frame
void Update () {
	
}

 void Spawner() {
     Vector3 pos = FindPos();
     pos += transform.position;
     Instantiate(prefabs, pos, transform.rotation);
 }


Vector3 FindPos() {
	 
     Vector3 pos = Vector3.zero;
     for (var i = 0; i < 1000; i++) {
	
         pos = Random.insideUnitCircle * diskRadius;
		 

         if (Vector3.Distance(pos, holeLocalPos) > holeRadius) {
             return pos;
         }
     }
     return pos;
 }

}

here is the result:

the circle should be like on the ground and not relative to the cube

You mean like this?:

pos = Random.insideUnitCircle * diskRadius;
pos = new Vector3 (pos.x, 0, pos.y); // Lay the circle down flat on the ground

Also, if you’re interested in optimizing your code, you can do the following then you won’t need the loop:

public Vector3 FindPos ()
{
	Vector3 pos = Random.insideUnitCircle;
	pos = new Vector3 (pos.x, 0, pos.y); // Lay the circle down flat on the ground
	pos = pos.normalized * (holeRadius + pos.magnitude * (diskRadius - holeRadius));
	return pos;
}
