Difference between Circle and Sphere

Both the Circle & Sphere both being 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-

  • A circle is a two-dimensional figure whereas, a Sphere is a three dimensional object.
  • A circle has all points at a 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.


Area of a Circle = \(\pi r^{2}\)

Area of a Sphere = \(4 \pi r^{2}\)

Volume of a Sphere = \(\frac{4}{3} \pi r^{3}\)

Ted was now curious to find the largest number. He asked 1, “Who is the largest number here?” 1 replied, “I don’t know, ask 2.”
Ted went to 2 who told him to ask 3. Similarly, every number asked Ted to ask the next greater number. After asking a lot of numbers he realized:
