Best Answer

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.

A sphere to a cone is the same as a circle is to a triangle but they are both 3 dimensional.

A cube is a three dimensional square, and a sphere is a three dimensional circle.

A sphere is a three dimentional shape, a circle is a two dimentional shape. You can't pick up a circle, it can only be drawn. In differential geometry, a one dimensional sphere is a point, a two dimensional sphere is a circle and a three dimensional sphere is what we call a "sphere", there is no limit to the number of dimensions a sphere can have.

A "great circle" is any circle on a sphere whose center is also the center of the sphere. The shortest distance between two points on the surface of a sphere is a piece of the great circle on which both points lie. A "small circle" is any circle on the sphere that's not a 'great' circle.

A small circle is a simple circle on a two dimensional plane. The great circle is the circle around a sphere that is on the plane that intersects with the center of the sphere. It is the reason that on a flat map the paths of planes seem to curve to go to and from Europe and the North American continent.

a sphere is a 3D circle like a ball 3D Items you can pick up they have three dimentions (they stand out) a circle is a 2D item like a pattern of circles 2D items have 2 dimentions (they're flat)

Sphere is whole a hemisphere is not

A hemisphere is half a sphere

A great circle is any circle on the surface of a sphere whose center is at the center of the sphere. The shortest distance between two points on the surface of a sphere is a part of the great circle that passes through them.

A sphere is three dimensional, a circle is not. So a tennis ball is sphere not a circle You can draw a circle on paper but is is not a sphere.
