You can find the measurement of a circle with just its width
how?
By multiplying it by pi
wtf is a pi?
pi is 3.14594839389383...
What? So it doesn't have an end?
No its an irrational number
Wtf is an irrational number?
Dude just trust me

Circles are infinite, Pi is infinite. Makes sense to me m8

>>11664646
op is a retard

you first measure circle's circumference and diameter and then you do division and you get pi

ancient people must've do those calculations with many different circles and they noticed that the result is always pi

how can pi even exist if perfect circles dont even exist

>>116646 by definition, a circle is the set of points, in two dimensions, that lie equidistant from a central point. The length of the perimeter of this shape devided by the distance between two opposite points yields a specific number we call Pi.

>>11665308
Given the commutative property of multiplication one can then use either the diameter or circumference and Pi to find the other

>>11664646
just because our numbering system makes irrational numbers that force us to make approximations doesn't mean those geometries do not have a length

How so?

I had expected more of an effort from mathematicians here.

Draw one.
You can't.
You are a perfect person.
Yet you can't draw a perfect circle.
Therefore perfect circles don't exist.

Even God is powerless to create a perfect circle. Qed.

"If we were to expand the electron up to be the size of the solar system, then we've measured its shape accurate to less than the width of a human hair,"

It's round
