LMGTFY - Let Me Google That For You have a look at the link…

 using UnityEngine;
 using System.Collections;
 
 public class Example : MonoBehaviour {
 
     public int numObjects = 10;
     public GameObject prefab;
 
     void Start() {
         Vector3 center = transform.position;
         for (int i = 0; i < numObjects; i++){
             Vector3 pos = RandomCircle(center, 5.0f);
             Quaternion rot = Quaternion.FromToRotation(Vector3.forward, center-pos);
             Instantiate(prefab, pos, rot);
         }
     }
 
     Vector3 RandomCircle ( Vector3 center ,   float radius  ){
         float ang = Random.value * 360;
         Vector3 pos;
         pos.x = center.x + radius * Mathf.Sin(ang * Mathf.Deg2Rad);
         pos.y = center.y + radius * Mathf.Cos(ang * Mathf.Deg2Rad);
         pos.z = center.z;
         return pos;
     }
 }

Alternative solution that uses the Random.onUnitSphere method. IMO Random.onUnitSphere * radius is more readable than math even though the math described above is definitely not complicated. YMMV.

public class PositionOnSphere: MonoBehaviour {
        public SphereCollider sphereCollider;
        private bool _active;
        private void OnValidate() => _active = sphereCollider != default;
        private void Start() {
            // As an example, just position the gameObject that this example component is attached to
            PositionSpawnedOnSphereCollider(gameObject);
        }
        private void PositionSpawnedOnSphereCollider(GameObject targetGameObject)
        {
            if (!_active) return;

            var positionOutsideSphere = Random.onUnitSphere * sphereCollider.radius;
            targetGameObject.transform.position = positionOutsideSphere;
        }

}
