dimensions
To a mathematician, a sphere and a circle are essentially the same thing, a collection of all the points that lie equidistant from a single point. (Think about this for a moment: If you took a piece of paper, then marked a point on the piece of paper with a dot, then marked all those places on the paper that are exactly, say, 1 inch away from the dot, you'd have a circle. Same thing with a sphere, but you'd have to mark all the points in three dimensions.) Mathematicians call circles 1-spheres, as creating them requires only a one-dimensional line, properly curved. Mathematicians call actual spheres 2-spheres, as creating them requires a two-dimensional surface. To mathematicians, the distinction between a 1-sphere and a 2-sphere is insignificant. They prefer to study n-spheres, spheres that can have any number of dimensions you like. No matter that we cannot imagine what even a 3-sphere would look like, sitting as it would in four-dimensional space. No matter that we cannot describe its appearance in English, or Japanese or Latin. Mathematics describes it with precision, and mathematics is the only language that counts. ( In general, an n-sphere of radius 1 is described by the equation {x ∈ Rn+1 | d(x,0) = 1} )

Circle is 2 dimensional. Sphere is 3 dimensional. This means you can draw a circle on a two dimensional plane like a sheet of paper but need a 3 dimensional environment like real world to play with three dimensional objects like a ball which is a sphere.

A circle is formed at the intersection of a plane with a sphere, like cutting a bowling ball in half. Your circle of friends forms your sphere of influence.

A circle is 2-dimensional, and a sphere is 3-dimensional.
The same basic mathematical idea applies to both: all points that are the same distance out from a center point. All you have to do is identifiy the center, and define the radius, and there you have it!
In a plane, it's a circle. I
In space, it's a sphere.

A circle in 3-dimensions is referred to as a sphere..like a tennis ball is a sphere..
