In the 18th century, Johann Heinrich Lambert was the first to prove that pi is an irrational number. However, his proof requires some pretty heavy-duty mathematics. In the 19th century Charles Hermite found a proof which is simpler but still requires requires knowledge of fairly advanced calculus.

Is every irrrational number a real number?
Yes every irrational and rational number is a real number.
Is -2.2 rational?
No 22*pi is not a rational number
Is pi 12 equal to a rational number?
Any multiple of or addition to or subtraction from PI is an irrational number. PI divided by PI is 1, a rational number. So is PI times 0 = 0
Is 22 pie rational?
No 22*pi is not a rational number
Is Rational number part of pi?
Yes. For example, if you take any truncated equivalent of pi then it will be rational.
Is every irrrational number a real number?
Yes every irrational and rational number is a real number.
Is number 1 divided 3 a rational number?
It is. A rational number is either an integer or a recurring decimal. An irrational number would be the square root of 2. There are also complex numbers that aren't rational or irrrational.
Is the square root of 17 rational or irrrational?
irrational
Is 0.16 pie a rational number?
(pi) itself is an irrational number. The only multiples of it that can be rational are (pi) x (a rational number/pi) .
Is 3.14 a rational or irrational number?
3.14 is a rational number pi is not. pi is not 3.14
Is 89 over 1 rational or irrrational?
Any number that can make a fraction with whole numbers on top and bottom is rational. 89 is a whole number, and so is ' 1 ', so it looks like you've nicely succeeded in defining a rational number.
Why is pi a rational number?
Pi is irrational.
Why the area of a circle with a rational radius must be an irrational number?
It the radius is r then the area is pi*r*r - which is pi times a rational number. pi is an irrational number, so the multiple of pi and a rational number is irrational.
What irrational number can be added to pi to get a sum that is rational?
Minus pi. Or minus pi plus any rational number. Here is how you can figure this out (call your unknown number "x", and let "r" stand for any rational number):x + pi = r To solve for "x", simply subtract pi from both sides. That gives you: x = r - pi
Is -2.2 rational?
No 22*pi is not a rational number
Is pi 12 equal to a rational number?
Any multiple of or addition to or subtraction from PI is an irrational number. PI divided by PI is 1, a rational number. So is PI times 0 = 0
Is 10 pi rational?
No 10*pi is not a rational number because it can't be expressed as a fraction
