[eli5] Why pie ? Can’t 1m form the circumference of a circle. why can pie form a prefect circle ?
In: 0
You can totally have a circle with a circumference of 1.
Such a circle would have a diameter of 1/pi
If the diameter is a whole (or even just a rational) number then the value for the circumference will have to have pi multiplied by something.
If the circumference is a whole (or even just a rational) number then the value for the circumference will have to have pi^-1 multiplied by something.
They can’t both be whole numbers or even just ratios of whole numbers.
This is what they mean when they talk about squaring the circle.
You can’t do it either one value or the other (or both) have to have an irrational component.
