WHAT IS Pi(π) ??

qThe number π is a mathematical constant. It is defined as the ratio of a circle's circumference to its diameter, and it also has various equivalent definitions. It appears in many formulas in all areas of mathematics and physics. It is approximately equal to 3.14159. It has been represented by the Greek letter "π" since the mid-18th century, and is spelled out as "pi". It is also referred to as Archimedes' constant.

Being an irrational number, π cannot be expressed as a common fraction, although fractions such as 22/7 are commonly used to approximate it. Equivalently its decimal representation never ends and never settles into a permanently repeating pattern. Its decimal (or other base) digits appear to be randomly distributed, and are conjectured to satisfy a specific kind of statistical randomness. It is known that π is a transcendental number: it is not the root of any polynomial with rational coefficients. The transcendence of π implies that it is impossible to solve the ancient challenge of squaring the circle with a compass and straightedge

Pi SYMBOL

Why,When & How Pi is used ??qPi is used to find the area and circumference of a circle. Pi is used to find area by multiplying the radius squared times Pi.

qPi is all around us and is constantly being used CONTINUOUSLY

Who invented Pi ??

vThe first calculation of π was done by Archimedes of Syracuse (287–212 BC), one of the greatest mathematicians of the ancient world.

vWhereas, WILLIAM JONES is recognized as the father of pi who in 1706 was a maths teacher & used a symbol for first time to explain the concept of pie
