Difference between Circle and Sphere

There are a few integral differences between a circle and sphere which separates them both in a lot of ways. Both the circle and sphere are different even if both are circular objects, thus, they create a lot of confusion in understanding them. Both seem to be similar but in reality, they have a huge difference between them. Let us have a deeper understanding of both the terms.

Key Differences between a Circle and Sphere:

  • A circle is a two-dimensional figure whereas, a Sphere is a three-dimensional object.
  • Area of a Circle = π r2 and Area of a Sphere = 4 π r2
  • A circle has no volume and the Volume of a Sphere =4/3π r3
  • A circle has all points at the same distance from its centre along a plane, whereas in a sphere all the points are equidistant from the centre at any of the axis.
  • We can only determine the surface are in case of a Circle, while in Sphere we can calculate the surface area as well as volume.
