Answer:
Yes, all spheres are similar to each other.
Step-by-step 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.
