A right-circular cone and a right-circular cylinder of the same diameter and length (A2) are positioned coaxially at a distance Lofrom the circular disk (A1) shown schematically. The inner base and lateral surfaces of the cylinder may be treated as a single surface, A2. The hypothetical area corresponding to the opening of the cone and cylinder is identified as A3.
