What is the difference between a circle and a sphere?

Answer 1

A circle is two dimensional; a sphere is three dimensional

AnswerA circle is a simple shape consisting of points in a plane (flat surface) which are equidistant from a given point called the center.

A sphere is a perfectly round geometrical object in three-dimensional space, such as the shape of a round ball. Like a circle in three dimensions, a perfect sphere is completely symmetrical around its center, with all points on the surface lying the same distance r from the center point.
