I hate this "area" argument!! The simple fact is that area does not equal mass nor does area equal volume nor does area equal gravity.

Check the units: when area (m^{2}) is multiplied by density (kg/m^{3}) we end up with kg/m which is non-sense.

I tried to show toShinAcethat the pizza argument is only applicable to cylinders with afixedlength but diameter varying with distance and nowgrapesis confused - we are talking aboutfrustumsnot cylinders.
