When you’re talking about geometry and circles, it’s easy to get confused about the difference between a circle and a sphere. The truth is, they are both round shapes, but that’s where the similarities end.
The main difference is a circle is a two-dimensional shape, while a sphere is a three-dimensional shape.
Before we move to the differences, let’s understand what are Circle and Sphere:
- Circle: Circles are flat, round figures that are completely enclosed by a line.
- Sphere: Spheres are three-dimensional, round figures that have no opposite sides.
Now, let’s move to Circle vs Sphere:
Major differences between Circle and Sphere
|A circle has no thickness.||A sphere has an entire inside and outside surface.|
|Circles can be divided into many equal parts for measuring things like circumference or area.||Spheres cannot be divided into equal parts.|
|A circle also has no volume.||A sphere has an entire inside and outside volume.|
|Circumference of a circle is 2πr.||Sphere does not have the circumference.|
|Examples of circle are coins, CD, wheels etc.||Examples of sphere are planets, oranges, globe etc.|
Note that sometimes, the question might also be asked as “distinguish between Circle and Sphere”.

- Difference between Moving Iron and Moving Coil
- Difference between Thorn Forests and Mangrove Forests
We hope you enjoyed this lesson on the differences between a circle and sphere. Remember that a circle is a two-dimensional object, while a sphere is three-dimensional. Both the circle and the sphere are mathematically perfect shapes, but they are different in appearance and meaning.
