Restrict gameobject inside a radius around my player

I need to restrict my Players hand inside a radius around the character. The game is 2D and the hand movement is basically exactly the same as: Madness Interactive (https://www.newgrounds.com/portal/view/118826)

[SerializeField] private float speed = 2f;
[SerializeField] private GameObject radiusCenter;
[SerializeField] private float radius = 0.5f;


void Start()
{
    Cursor.visible = false;
}



void Update()
{

    Vector3 playerPos = radiusCenter.transform.position;
    Vector3 playerToHand = this.transform.position - playerPos;


    var moveDirection = new Vector3(Input.GetAxis("Mouse X"), Input.GetAxis("Mouse Y"), 0);

    float DistanceToRadius = Vector3.Distance(playerPos, playerToHand);


    transform.position += moveDirection * speed * Time.deltaTime;
    
    

    float angle = Mathf.Atan2(playerToHand.y, playerToHand.x) * Mathf.Rad2Deg;
    transform.rotation = Quaternion.AngleAxis(angle, Vector3.forward);

}

I cant figure out the way to keep my players hand inside a set radius around my player, see pictures below for further explanation:

I thought maybe I could get a float value from playerPos and playerToHand and create a IF-statement that restricts the hand from going outside the set radius float, but I didnt get it to work...

EDIT 1: The hand is a child of my player. I use a gameObject in the center of my player as radiusCenter which my hand rotates around.

One very simple way to check if the hand is too far away is to use this line of code:

<movement code here>
if (Vector3.distance(playerPos, transform.position) > radius)
{
    transform.localPosition = transform.localPosition.normalized * radius;
{

This will make it so if the hand will be outside the circle after the move, it will just put the hand on the circle.
