Creating Objects In Circle Starting at the top.

I am currently using this to evenly distibute a constantly changing amount of objects in a circle.

float pointNum = (i*1.0f)/golemTierCount;

             float angle = pointNum * Mathf.PI * 2 - offset;
             
             float x = Mathf.Cos(angle) * radius;
             float y = Mathf.Sin(angle) * radius;
             Vector3 pointPos = new Vector3(x, y) + UI.gameObject.transform.position;

And it works great but it seems to start at the right when odd and the top when even and i cant seem to find a way to get it to start at the top no matter how many objects there are.

Any help would be appreciated.
