# Who first discovered the number pi?

## Who first discovered the number pi?

Archimedes of Syracuse

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.

**Who discovered pi in India?**

Aryabhata

Mathematics in India has a rich history. Indian mathematicians Madhava and Aryabhata made very significant contributions in finding the exact value of π (pi).

**What value is pie?**

approximately 3.14

Succinctly, pi—which is written as the Greek letter for p, or π—is the ratio of the circumference of any circle to the diameter of that circle. Regardless of the circle’s size, this ratio will always equal pi. In decimal form, the value of pi is approximately 3.14.

### Which is known as Ludolf number 1 point?

Ludolph Van Ceulen was a German mathematician who is famed for his calculation of π to 35 places. In Germany π used to be called the Ludolphine number.

**What was PI called in India?**

With Aryabhatta (476 AD), a new era of mathematics dawned in India. Aryabhatta approximated Π = 62832/20000 = 3.1416. This was astonishingly correct to 4 decimal places (better than 22/7, which is correct only to 2 places). The Indian values of Π (√10, 62832/20000) were later included in Chinese and Arabs literature.

**How did Ludolph van Ceulen calculate pi?**

He inscribed a hexagon inside a circle and also circumscribed another hexagon outside the same circle. He then calculated perimeters and diameters for both these hexagons, leading to an upper and lower bound for Pi.

#### Who had the digits of pi engraved on his tombstone?

Ludolph van Ceulen

The tombstone of Ludolph van Ceulen in Leiden, the Netherlands, is engraved with his amazing 35-digit approximation to pi. Notice that, in keeping with the tradition started by Archimedes, the upper and lower limits are given as fractions rather than decimals.
