Except for tangents a plane through a sphere forms a circle, thus encompasses a circular disc. > 2) the answer should read "that of" 'a circle' "with equal radius" Do you mean "with equal radius" to that of the sphere?

Which also got rid of the second circular disc surface on that half. > Gryphon 5) it is assumed that "slicing" a sphere means passing a plane through it --johnathan a. tainter P.S. This question is not so much WRONG as it is excessively loose with geometric vocabulary. This poster is not so much WRONG as he is excessively loose in a computer environment.
