eli5 Why is the circumference of a circle divided by its diameter always (for the majority) equal to pi?
In: 8
If it didn’t, it wouldn’t be a circle. Part of the definition of a circle is that *every* point on the line is the same amount of distance from the center, that distance being the radius. With that rigid of a definition, there’s only one way to change its shape which is to make the whole thing bigger or smaller by a specific proportion.
People stated things similar to this but its the opposite. Pi is defined that way not that the other way around. Since all circles follow this because they are perfect circles it always works.
