Does pi really equal 4?
The limit is a circle. Since the jagged curve gets closer and closer to the circle and always has length 4 we can see that the perimeter of the circle has length 4. But the perimeter length is also equal to π. Therefore, π is 4.

Is 4 times pi irrational?
4 is an integer and pi (π) is the ratio of a circle's circumference to its diameter and is best known as 3.14. However, pi is an irrational number with an infinite number of decimals: 3. 1 4 1 5 9 2 6 5 3 5 8 9 7 9 and so on. If 4 is the diameter of a circle, then 4 times pi is the circumference of that same circle.
Why is 3.14 called pi?
It was first called "pi" in 1706 by (the Welsh mathematician) William Jones, because pi is the first letter in the Greek word perimitros, which means "perimeter."
