    or is that seriously a three dimensional shape?

    i looked it up yo double check and stuff came up as a sphere being 2-d .. so i was second guessing myself this whole time.

    yes it's C. Think of a circle... it has a center and all distances from the center to the circumference are the same length. This is analogous to the sphere where the distances from the center of the sphere to the surface of the sphere are the same length

    well technically a sphere is 2d(its very confusing) but in most cases when we say sphere we are talking about option 3.

    two dimensional would be a circle... it would be flat. three dimensional is when it pops up... think 3D movies :) so spheres are the pop out versions of circles so i would say C is the best choice... @zzr0ck3r oh really?! they're considered 2D? i didn't know that :P lol

    A sphere is "surface , wrapped into a ball "

    well thatas what i thought! and then it came up a 2D sphere and im sitting here like, nahh that cants be it, but i cant get this wrong cause then ill just feel stupid, but 2D, really? lol. im so glad i have you guys!

    A Ball in 2d is a circle, and in 3d is what we call a sphere, and there are balls in R^n for any n

    which is what this question( I believe ) is calling a sphere.
