WebAs the number of sides increases, it becomes a more accurate approximation of a circle. Finally, when the polygon had 96 sides, he was able to determine that the value of pi lay between 31⁄7 and 310⁄71. The midpoint puts pi at 3.14159 which is over 99.999999% accurate. Method of Exhaustion WebA common fraction approximation of pi is /, which yields approximately 3.14285714. This approximation is 0.04% away from the true value of pi. While this approximation is accepted for most of its use in real life, the fraction 355 / 113 {\displaystyle 355/113} is more accurate (giving about 3.14159292), and can be used when a value closer to pi is needed.

WebDec 15, 2024 · Archimedes found his approximation to Pi by inscribed polygons. Start with a circle of radius 1 and a suitable starting polygon and solve for an inscribed polygon of 96 sides. Next, start with a unit circle and appropriate inscribed regular polygon to approximate Pi using a regular inscribed n-gon with 4096 sides. Weba rather inaccurate approximation to pi. Each time the number of sides is doubled, the approximation gets better. Archimedes used basic trigonometry to ﬁgure out how to compute the perimeter of each “doubled” polygon from the perimeter of the one before. His ﬁnal result was that πlies between 3 1/7 and310/71.

WebPi is by definition the ratio of a circle's area to its radius 2 (A = pi*r 2). So we draw a regular polygon outside a circle (with radius 1 unit for simplicity) and one inside the circle, calculate the areas of the polygons, and we know that the area of our circle is between the two values, and we can calculate a max and min approximation for pi. http://pi3.sites.sheffield.ac.uk/tutorials/week-7
