No, it isn't.  They got the spherical earth from such things as ships
disappearing over the horizon mast first.  And Aristothenes (if I've
remembered his name correctly) estimated the size of the earth fairly
accurately by measuring the shadow of a stick in two locations that
were on the same longitude.  Those are the sort of discoveries that
would have eventually reached the tana'im in EY, but would have taken
a while longer to get to the amora'im of Bavel.
