Through observation, he hypothesised that perimeters of polygons drawn inside and outside of a circle would be close to the circumference of the circle. The Archimedian methodĪrchimedes of Syracuse was the first to attempt calculating pi. Equating 24/25 to the ratio of lengths 6$r$/(2 $\pi r$) and rearranging gives pi as 25/8 or 3.125. 24/25 is one of the constants, and it conforms with the ratio of a perimeter of a hexagon, with side length $r$, inscribed in a circle of radius $r$, to the circumference of the circle.

Many Babylonian tablets were found in Susa, and one of them shows a list of mathematical constants. The Babylonians, on the other hand, had an estimate of about 3.125. Comparing this measurement with the formula of a circle’s area, Egyptians concluded that pi They squared the measurement to get the area of the square, which is 256$r^2$/81. Within a given circle in which the diameter is 2$r$, Egyptians took away 1/9 of its diameter, which leaves 16$r$/9. They hypothesised that the area of a square with a side length that is 8/9 of a circle’s diameter would be equal to the area of the circle. A translation of a part of the Rhind Papyrus states how the approximation was derived. The Egyptians’ approximations of pi were indicated through the Rhind Papyrus: they had an approximation of about 3.160. The existence of pi was known long ago–almost 4000 years ago. You can find the value of pi yourself when you measure around the edge of a circle and divide it by the measurement across the circle. In other words, pi is the ratio of the circumference of a circle to its diameter.
