I am confused about some questions II-A
Hi for 9.21 what does "put" mean? for 9.30, if the sphere is inscribed, shouldn't the intersections just be a point (radius=0)?
In 9.21, "put" should mean "fit" or "inscribe".
In 9.30, the sphere is touching the side surface of the frustrum, so it is a circle.
