Are you burdened by the evil of memorizing a sequence of random and intangible numbers simply to perform a simple operation like calculating the area of a circle? Do you feel oppressed by the regime that has drilled into our minds the inevitable infinitude of numbers that make up the irrational constant π? Today is the day to shake off the shackles! Read on, and you, too, will discover how to unravel the hidden truth that pi actually equals 3.

1Take out a sheet of paper. If you are really going to stick it to the man, you might want to use something other than the everyday 81/2" x 11" sheets of paper.

2Set up your proof. At the top of the paper, write that a=b.
 Square both sides of the equation.
a^{2} = b^{2}  Rewrite this in another form. This will be your starting point for the proof.
a^{2} = ab
Advertisement  Square both sides of the equation.

3Set up a secondary equation. Simply multiply both sides of your most recent equation by 3. You will need to incorporate this into your proof later.
 3a^{2} = 3ab

4Perform the following operations:
 Multiply both sides of the starting point for your proof, a^{2} = ab, by π.
πa^{2} = πab  Subtract one (equal) half of your secondary equation, 3a^{2} = 3ab, from each side.
πa^{2}  3ab = πab  3b^{2}  Add 3ab and subtract πab on both sides.
πa^{2}  πab = 3ab  3b^{2}  Add ab and subtract b^{2} on both sides.
πa^{2}  πab + ab  b^{2} = 4ab  4b^{2}  Factor out common terms.
πa(ab) + b(ab) = 4b(ab)  Remove common terms.
πa + b = 4b  Subtract b from both sides.
πa = 3b  Substitute a for b (since a = b).
πb = 3b  Remove common terms.
π = 3
 Multiply both sides of the starting point for your proof, a^{2} = ab, by π.

5Let out a gasp of incredulity! How many years of unnecessary pain did you endure in math, calculating the area of a circle with the clearly fabricated 3.14, or, even worse, 3.1416?

6Take a moment to relish your newfound freedom by calculating areas and volumes with the new value of π: 3. Now, it's perfectly easy: Given a circle of radius 10 units, the area is π*radius^{2}, or 3*10^{2} = 300 units^{2}. Ah, the power!

7Why stop at π? You may have been one of the poor, enslaved students who also used 2.718 for e or 1.414 for the square root of 2. Be free of all of them!Advertisement

Tips
 Discuss. Show this to a person to share your opinion with, like a math teacher, and ask if it is mathematically correct.Thanks!
 Use this as a fun trick to confuse your friends, parents, or math teacher.Thanks!
 Can you spot the mistake? Hint: it’s in πa(ab) + b(ab) = 4b(ab). That’s because a = b, so ab = 0.Thanks!
 If you can prove that π is equal to 3, then you can also prove that π is also equal to any other number and that &pi is actually an infinite series of numbers.Thanks!
Warnings
 Do not use this in your math class or in real problems.Thanks!
 Many will try to tell you that you've got it all wrong and that π is an irrational number approximately equal to 3.1415926535897932384626433... They may even try to show "proofs" of this using phrases like "infinite summation" and "convergence". Maybe they will try to "show you the light" by drawing circles and showing how to estimate π. Well, it's their argument that is circular! Just remember that the people that fabricated those phrases and arguments are the same that fashioned these vicious lies about π! Imagine: A number whose digits are random and go on forever! Inconceivable!Thanks!
 While the article is amusing, the math is incorrect. PI = (Circumference of a circle)/(Diameter of a Circle). Using similar math as the article, I can prove that Pi is equal to 10, 20 or any other number (even 1!).Thanks!
