Spawn Floors To Fill Radius, And Remove Out Of Bounds Floors.,Spawn To Fill Radius

Hello, I am trying to make a system that spawns floor tiles (each 10x10 units) next to eachother within a certain radius, and removes the floor tiles that have their center point outside the radius. I do have functions that go about spawning floors around a center floor tile. But this will just create one circle around the center tile, instead of however many are nessecary to fill up a larger radius (currently a radius of 50 units).

Can/Should I use this approach to make it work the way I want to? If not, how else do I go about this?

 private Vector2[] PlaceFloorsAround(Vector2 currentFloorXZ)
     {
 
         Vector2[] newXZs = {
             new Vector2(currentFloorXZ.x + spawnOffset, currentFloorXZ.y),
             new Vector2(currentFloorXZ.x - spawnOffset, currentFloorXZ.y),
             new Vector2(currentFloorXZ.x, currentFloorXZ.y + spawnOffset),
             new Vector2(currentFloorXZ.x, currentFloorXZ.y - spawnOffset),
             new Vector2(currentFloorXZ.x -10.0f, currentFloorXZ.y - 10.0f),
             new Vector2(currentFloorXZ.x + 10.0f, currentFloorXZ.y - 10.0f),
             new Vector2(currentFloorXZ.x + 10.0f, currentFloorXZ.y + 10.0f),
             new Vector2(currentFloorXZ.x - 10.0f, currentFloorXZ.y + 10.0f),
         };
 
 
         foreach (Vector2 newXZ in newXZs)
         {
             if (canSpawnFloor(newXZ))
             {
                 Instantiate(floorPrefab, new Vector3(newXZ.x, floorHeight, newXZ.y), Quaternion.identity, transform);
             }
         }
 
         return newXZs;
     }
 
     private bool canSpawnFloor(Vector2 newXZ)
     {
         LayerMask layerMask = LayerMask.NameToLayer("Floor");
         Collider[] colliders = Physics.OverlapSphere(new Vector3(newXZ.x, floorHeight, newXZ.y), spawnCheckRadius, layerMask);
 
         if (colliders.Length == 0)
         {
             return true;
         }
 
         return false;
     }
