We are given a large circle with center $O$ and a diameter $a$, meaning the radius is $R = \frac{a}{2}$. Then, there is another smaller circle with center $O’$ touching the first circle’s circumference from the outside. This second circle has a diameter $b$, so its radius is $r = \frac{b}{2}$. If we project the center of the smaller circle $O’$ onto the vertical line passing through $O$, we name that projected point $P$.
