Radius too long

This piece of code is supposed to draw a long between an object and the point it’s “driving” around using it’s velocity and angular velocity. For some reason, though, the radius given is way longer that it’s supposed to be:

AngularVel = m_Rigidbody.angularVelocity.y;
Vel = m_Rigidbody.velocity.magnitude;
//Vel = transform.InverseTransformDirection(m_Rigidbody.velocity).z; same result
float radius = Vel / (AngularVel * Mathf.Deg2Rad);
Quaternion RadiusDirQuat = Quaternion.AngleAxis(m_Rigidbody.rotation.eulerAngles.y + 90, Vector3.up);
Vector3 radiusDir = RadiusDirQuat * Vector3.forward;
Debug.DrawRay(m_Rigidbody.position + Vector3.up, radiusDir * radius, new Color(1, 0, 0.5f, 1));

I’m using this article for reference: Motion in a Circle - Mathematics A-Level Revision

AngularVel is already in radians per second. This should be added to the docs tbh.
