Question

Are all spheres similar?

Answer 1

Yes, all spheres are similar to each other.

Explanation:

We have to tell all the spheres are similar.

As the spheres has no other configuration except for being perfectly round three-dimensionally. Actually a sphere's only important measurement is its radius since diameter, circumference, and everything else depends on the radius anyway. All are of similar shapes as only radius differs.

Hence, all spheres are similar to each other.

Answer 2

All spheres are similar because there are no other configuration of spheres except for being perfectly round three-dimensionally. Similar shapes are shapes where angles are similar as well as the sides which can just be determined through ratio and proportion
