I have this function that moves the object around a circle:

 void arrangeCardsInHand(Player newPlayer){
         
         int numCards = newPlayer.Hand.Count;
         var centrePos = new Vector3(0, 300 ,0);
         
         for (var cardNum = 0;cardNum < numCards;cardNum++) {
             var i = (cardNum * 1.0 / numCards);
             
             //angle in radians, full circle has a radian angle of 2PI, so we find the radian angle between 
             //2 of our points by dividing 2PI by the number of points
             var angle = (float)(i * Mathf.PI * 2);
             
             var radiusX = 10000.0;
             var radiusZ = 4300.0;
             
             var x =(float)( Mathf.Sin (angle) * radiusX);
             var z = (float)(Mathf.Cos (angle) * radiusZ);
             
             var cardName = newPlayer.Hand[cardNum].cardName;
             GameObject.Find(cardName).transform.position = new Vector3(x, 0 ,z) + centrePos;
             
             
         }
         
     }

I want the cards to be arranged in the top arc of the circle (1/4 of a full circle).

I have no idea how to work out the starting and the ending point into this formula tho. I'm also open for other ideas (like beziers or w/e) if you think this is not the best solution for what I want to do.

Any answer is appreciated.
