Thanks, Narasimham.

Agreed about the area - why is the volume also not a function of the
slant length/arc (in the general case)? Consider the case where the
slant is very sharp (almost parallel to the y axis) versus just
parallel to the x-axis - are the volumes of the solid of revolution the
same? Since the volumes will be different, the volume should also be a
function of the slant length (or infinitesimal length along the curve
ds) and not just a function of the x component dx. Am I missing
