unity set position from rotation around point code example

Example 1: rotatearound unity

using UnityEngine;//Attach this script to a GameObject to rotate around the target position.
public class Example : MonoBehaviour
{
    private Vector3 target = new Vector3(5.0f, 0.0f, 0.0f);    void Update()
    {
        // Spin the object around the world origin at 20 degrees/second.
        transform.RotateAround(target, Vector3.up, 30 * Time.deltaTime);
    }
}

Example 2: rotate vector3 around pivot point unity

public Vector3 RotatePointAroundPivot(Vector3 point, Vector3 pivot, Vector3 angles) {    return Quaternion.Euler(angles) * (point - pivot) + pivot;  }
