Who was the first person who discovered pi to be 22 over 7?

Archimedes computed upper and lower bounds of π by drawing a regular hexagon inside and outside a circle, and successively doubling the number of sides until he reached a 96-sided regular polygon. By calculating the perimeters of these polygons, he proved that 223/71 < π < 22/7 (that is, 3.1408 < π < 3.1429).

Who invented pi 22 7?

Archimedes (c. 250 bce) took a major step forward by devising a method to obtain pi to any desired accuracy, given enough patience. By inscribing and circumscribing regular polygons about a circle to obtain upper and lower bounds, he obtained 223/71 < π < 22/7, or an average value of about 3.1418.

Who first discovered the value of pi?

The Egyptians calculated the area of a circle by a formula that gave the approximate value of 3.1605 for π. The first calculation of π was done by Archimedes of Syracuse (287–212 BC), one of the greatest mathematicians of the ancient world.

Is 3.14 or 22 7 more accurate?

In the past, many math books listed Pi as 22/7. Again, this is just an approximation but it is better than the value of 3 (actually 22/7 is closer to Pi than just writing 3.14). The early history of mathematics covers many approximations of the value of Pi.

Why is pi 22 divided 7?

It is known that \pi is an irrational number and therefore cannot be expressed as a common fraction. Its value is approximately equal to 3.141592. Since Archimedes was one of the first persons to suggest a rational approximation of 22/7 for \pi, it is sometimes referred to as Archimedes' constant.

How do you prove that pi is 22 7?

Proof:
  1. Take a circle with a diameter of 1 unit.
  2. The circumference of this circle would be π * 1, which is equal to π units.
  3. Now, let's take another circle with a diameter of 7 units.
  4. The circumference of this circle would be π * 7, which is equal to 22 units (approximately).

Does pi end in math?

In decimal form, the value of pi is approximately 3.14. But pi is an irrational number, meaning that its decimal form neither ends (like 1/4 = 0.25) nor becomes repetitive (like 1/6 = 0.166666...). (To only 18 decimal places, pi is 3.141592653589793238.)

Is pi bigger than infinity?

Is Pi bigger than infinity? Pi is finite, whereas its expression is infinite. Pi has a finite value between 3 and 4, precisely, more than 3.1, then 3.15 and so on. Hence, pi is a real number, but since it is irrational, its decimal representation is endless, so we call it infinite.

Should I use 3.14 or 22 7?

Explanation: If you see in your problem that there are a lot of fractions, then you can go ahead and use 227 so that you could cancel some terms out and simplify your calculations. But if you see in your problem that there are decimals and whole numbers you can go ahead and use 3.14 .
