How did aryabhatta discover the value of pi?
3.1416
Aryabhata discovered an approximation of pi, 62832/20000 = 3.1416. He also correctly believed that the planets and the Moon shine by reflected sunlight and that the motion of the stars is due to Earth’s rotation.
Who calculated the value of pi to 4 decimal places?
The record of manual approximation of π is held by William Shanks, who calculated 527 digits correctly in the years preceding 1873….Summing a circle’s area.
| r | area | approximation of π |
|---|---|---|
| 3 | 29 | 3.22222 |
| 4 | 49 | 3.0625 |
| 5 | 81 | 3.24 |
| 10 | 317 | 3.17 |
Who was the Indian mathematician found the value of correctly upto 4 decimals?
Aryabhatta (476 – 550 C.E.) , the great Indian mathematician and astronomer, found the value of π correct to four decimal places (3.1416). Using high speed computers and advanced algorithms, π has been computed to over 1.24 trillion decimal places !
How accurately do we know pi?
After all, every additional digit you have yields ten times the accuracy. So if you know π out to twenty digits, that’s not 20 times more accurate than just “3”, that’s 100,000,000,000,000,000,000 times more accurate. Every major civilization has been aware of π and have relied on various approximate values.
What did aryabhatta research?
Aryabhatta was an extraordinary teacher and scholar who had immense knowledge about mathematics and astronomy. He suggested the heliocentric theory which proved that the sun is located in the centre of the solar system and all the planets revolve around it.

What is the most accurate value of pi?
The most accurate value of pi is 50,000,000,000,000 digits, and was achieved by Timothy Mullican (USA) in Huntsville, Alabama, USA, on 29 January 2020.
How did Archimedes calculate the value of pi?
Archimedes’ method finds an approximation of pi by determining the length of the perimeter of a polygon inscribed within a circle (which is less than the circumference of the circle) and the perimeter of a polygon circumscribed outside a circle (which is greater than the circumference).
What are the decimal places of pi?
That’s because pi is what mathematicians call an “infinite decimal” — after the decimal point, the digits go on forever and ever. When starting off in math, students are introduced to pi as a value of 3.14 or 3.14159. Though it is an irrational number, some use rational expressions to estimate pi, like 22/7 of 333/106.
How many decimal places are there in the value of pi?
31.4 trillion decimal places
In honor of Pi Day, today March 14 (represented as 3/14 in many parts of the world), we’re excited to announce that we successfully computed π to 31.4 trillion decimal places—31,415,926,535,897 to be exact, or π * 1013.
What 3 things did Aryabhata discover?
How did Aryabhatta discovered zero?
George Ifrah, a French Mathematician stated that the concept and understanding of zero as a ‘digit’ was first given by Aryabhata in his place value system because the counting system of digits is not possible without the place value system or zero.
What did Aryabhata say about Pi?
Aryabhata also gave an accurate approximation for Pi. In the Aryabhatiya, he wrote: “Add four to one hundred, multiply by eight and then add sixty-two thousand. the result is approximately the circumference of a circle of diameter twenty thousand. By this rule the relation of the circumference to diameter is given.”
What is Aryabhatta’s value of the size of the Earth?
Aryabhata calculated the circumference of the Earth as 39,968 kilometers while the actual circumference is 40,075 kilometers. Thus Aryabhatta’s value of the size of the earth is only 0.2\% smaller than the actual size.
What is the contribution of Aryabhatta in the development of Indian numerals?
In Aryabhatiya, Aryabhatta introduced a system of numerals in which he used letters of the Indian alphabet to denote numbers. His numeral system allowed numbers up to 10 18 to be represented with an alphabetical notation. It is considered that Aryabhatta was familiar with the concept of zero and the place value system.
Who discovered the exact value of Pi?
Aryabhata discovered this value independently and also realised that π is an irrational number. He had the Indian background, no doubt, but excelled all his predecessors in evaluating π. Thus the credit of discovering this exact value of π may be ascribed to the celebrated mathematician, Aryabhata.
