# Who discovered the pi?

Archimedes did sometime between 287-212 BC.

# How was pi discovered?

The early history of N (pi) from textual sources roughly parallels the development of mathematics as a whole. Early evidence points toward use of an approximation for the len…gth of 'circumference' with respect to its 'radius' (~ 3 1/7) in the designs of the pyramids in Egypt. The Great Pyramid (2500 BC) was built with a perimeter of 1760 royal cubits (1 royal cubit ~ 20.64 inches or 525 mm) and a height of 280 cubits; the ratio 1760/280 ~ 2π ~ 6.29. (N ~ 3.14) Pi was discovered by the Greeks by a process called exhaustion. They observed that any polygon could be divided into triangles whose areas could be combined to get the area of the shape, so they tried the same thing with circles. They then factored in the radius of the circle, and they found pi. These triangles can theoretically get infinitely smaller, which is why pi is an irrational number.

# Who discover value of pi?

The Egyptians and the Babylonians are the first cultures that discovered Pi about 4,000 years ago.

# Why was pi discovered?

So Marie Callendar's would have something to sell, NO SERIOUSLY! The Egyptians used an approximation of Pi in the 20th century B.C. and probably used it for construction and b…uilding. It is often important to know the circumference of a circle and it is Pi times its diameter. They may have been the first to discover it. A century later, the Babylonians used Pi. As time passed, the approximation they used improved.

# What is Pi and who invented or discovered Pi?

Pi is the relationship between the diameter and the circumference of a circle.

# What did Archimedes discover about pi?

# Who was the person who discovered pi?

# How did euclid discover pi?

he didn't.

# How do you discover pi?

First draw a circle using a compass. Now, use a piece of string to help measure the circumference of the circle. Now measure the diameter of the circle. To discover Pi divide… the circumference by the diameter.

# Are all the digits of pi discovered?

Answer: No. Pi is irrational; we could never find the last digit,because the digits go on forever. Also, being irrational means thatthe digits don't repeat periodically.

# Who discovered pi in maths?

Historically, Ancient Egyptians are the first who introduced a reasonably accurate value for the ratio of the circle area and its square radius. They used an approximate value… of 3.1605 for pi The ancient Babylonians generally calculated the area of a circle by taking 3 times the square of its radius (=3), but one Old Babylonian tablet (from ca. 1900-1680 BD) indicates a value of 3.125 for pi. The first theoretical calculation of a value of pi was that of Archimedes of Syracuse (287-212 BD), one of the most brilliant mathematicians of the ancient world. Archimedes worked out that 223/71 < pi < 22/7 The Greek letter π (pi) was adopted for the number from the Greek word for perimeter "περίμετρος", first by William Jones in 1707, and later popularized by Leonhard Euler in 1737. The constant is occasionally also referred to as the circular constant or Archimedes' constant.

# Who discovered pi and screamed eureka?

Archimedes was the first to discover it accurately but pi was around in the time of early egyptians and mesopotamians...so pi has been around for a long time Archimedes did, o…ne day while he was in the bath tub. The sudden realization made him so excited that he ran down the hall yelling "Come here, Watson, I want you !" Eventually he reached the kitchen, where the door slammed behind him, and an apple fell on his head, stunning him temporarily. Realizing the gravity of his situation, he reached for the key dangling from the wall by a string, but it gave him such an electric shock that he ran back out of the kitchen and up to the bath chamber to fetch his robe. His heart pounding now, he sank onto his bed, marveling and exclaiming "What hath god wrought!" at the wonder of it all, and as he tried to relax and to calm himself, he muttered to himself in a soothing tone, "We have nothing to fear but ... fear itself."
