Let's look at your link definition:<quoted text>

In geometry, a disk (also spelled disc) is the region in a plane bounded by a circle.

In geometry, a disk (also spelled disc) is the region in a plane bounded by a circle.

plane(geometry) definition - a plane is a flat, two-dimensional surface.

A circle is two dimensional being it has the dimensions of height and width but not depth, therefore is two dimensional.

None of the above define a 3 dimensional sphere, which has height and width and depth. Not even from your definition link of disk.

So let's look at that again. A disc or disk is two dimensional like a circle. Nice try though. May I suggest you take a geometry class and maybe learn something new?
