Ok, this is a really stupid question but it is something that is really confusing me. I am confused on the concepts of dimensions, for example of a sphere and how they relate to Euclidean geometry. A sphere in 2 dimensions using Euclidean 3 dimensional geometry doesn't really make too much sence to me. I always thought of a sphere as having 3 dimensions so im confused. I understand if its written on paper it is obviously in 2 dimensions but im still confused, and what about even higher dimensions, how do those work as far as Euclidean geometry? I'm just really confused and any help would be great. Thanks
