# 8 Bad Ass Difference between Circle and Sphere

What is the difference between circle and sphere?

Both a circle and sphere are circular objects. These two objects tend to cause a lot of confusion among pupils in kindergarten.

The lesson provides the core difference between circle and sphere in tabular and point form for easier understanding.

## What Is A Circle?

A circle is a plane and a round figure whose limit consists of equidistant points from a center. It is therefore said to be a two-dimensional figure and a plane.

Main Properties of A Circle

1. The center is the point equidistant from the points on the circle
2. Radius is the line from the center joining any point on the circle
3. Diameter is a line that passes through the center and the endpoints lie on the circle.
4. The circumference is the length of one circuit along the circle
5. A chord is a line segment whose endpoints lie on the circle
6. Tangent is a coplanar straight line that touches the circle at a single point
7. Arc is any connected part of a circle

## What Is A Sphere?

A sphere is a solid and round figure whose points on the surface is equidistant from the center. It is a three-dimension figure and it has a volume.

Main Properties of a Sphere

1. The ratio of the distance of its points from two fixed points is constant.
2. The contours and plane sections are circular
3. It has constant width and girth
4. Does not have a surface center
5. The curvature is constant
6. Has the greatest volume and smallest surface area

## Core Difference between Circle and Sphere

1. A circle is a round figure in a plane while the sphere is a round object in space.
2. A circle is a 2D figure while a sphere is a 3D figure
3. The area only is calculated from a circle while both area and volume on a sphere
4. Examples of circles are bracelets and tires while for spheres are tennis balls and planets.

## Summary

Both a circle and sphere are perfect symmetry around their centers. the core difference between circle and sphere is the dimension where a circle is a two-dimension figure while a sphere is a three-dimensional object.
