Yes.  Expecting the degree symbol to be mangled, that's why I wrote
"i.e. the thirtieth parallel north."

Yes.  Archimedes is often called the greatest mathematical genius to ever live;
and the measures of a sphere are among his greatest discoveries.

(A well-known(?) list of the greatest mathematicians in ranked order shows
Archimedes as 2nd to Isaac Newton, but that's because the latter man had
enormous historical importance while Archimedes -- way ahead of his time --
had rather little.)
