Great. I see that he implemented both sets of equations along with the test

I see two red circles and two blue circles. The red circles are the
inner and
outer radii. One of the blue circles shows the inner edge of the

the purpose of the other blue circle is a mystery to me.

What is the purpose of the second blue circle?
