Question

why circle is better than square​

Answer 1

Answer:

Circles appeal to people because they are easier to understand than shapes and objects with hard lines. The eye is drawn to circles and the information contained within, and they are faster and easier for the brain to process than hard-edged squares and rectangles. ... Our “fovea-eye” is even faster in recording a circle.

Answer 2

Explanation:

circle takes the lowest possible surface area for a given length of material

for example if you have 16 long wire

bent it in shape of square or any other shape it will have more area than circle formed by the same wire
