Is this training or actual end item engineering design work?
You need a positional tolerance relative to datums defining the axis that need to intersect as well as and end of the cone feature.
Similar application (except internal features) See ASME Y14.5M-1994:
Paragraph 5.6, Figure 5-36
and if the "attached to the cone" feature is actually non-circular, see ASME Y14.5M-1994:
Paragraph 5.9.1 and Figure 5-41 Bi-Directional Positional Tolerancing.
