where C is the circumference of a circle, d is the diameter, and r is the radius.More generally, = where L and w are, respectively, the perimeter and the width of any curve of constant width.

The number π (/ p aɪ / ⓘ; spelled out as "pi") is a mathematical constant, approximately equal to 3.14159, that is the ratio of a circle's circumference to its diameter.It appears in many formulae across mathematics and physics, and some of these formulae are commonly used for defining π, to avoid relying on the definition of the length of a curve.
Emma Haruka Iwao (born April 21, 1984) is a Japanese computer scientist and cloud developer advocate at Google. [5] [6] In 2019 Haruka Iwao calculated the then world record for most accurate value of pi (π); which included 31.4 trillion digits, exceeding the previous record of 22 trillion.
Mathematical "graph paper" is formed by imagining a 1×1 square centered around each cell (x, y), where x and y are integers between − r and r. Squares whose center resides inside or exactly on the border of the circle can then be counted by testing whether, for each cell (x, y), +.
SINGAPORE (Reuters) -The dollar bounced, long-dated bond yields were up and Asian stocks surged after the Federal Reserve announced a 50-basis-point rate cut and flagged a measured easing cycle ...
Pi Day is an annual celebration of the mathematical constant π (pi). Pi Day is observed on March 14 (the 3rd month) since 3, 1, and 4 are the first three significant figures of π, and was first celebrated in the United States. [2] [3] It was founded in 1988 by Larry Shaw, an employee of a science museum in San Francisco, the Exploratorium.
Comparison of the convergence of the Wallis product (purple asterisks) and several historical infinite series for π. S n is the approximation after taking n terms. Each subsequent subplot magnifies the shaded area horizontally by 10 times.
