Question 185
The following figure shows a segment $AB$, its midpoint $C$ and the semi-circumferences of diameters $AB$ e $AC$. a center circle $P$ It is tangent to the two semi-circumferences and also to the segment $AB$. being $AB=8~\mathrm{cm}$, e $O$, the midpoint of $AC$, ask yourself:
a) what is the perimeter of the triangle $OCP$?
b) What is the radius of the center circle $P$?
