INTODUCTION OF PI(π)
Pi (π) is a mathematical constant that is the
ratio of a circle's circumference to is
diameter, and is approximately equal to
3.14159. It has been represented by the
Greek letter "π" since the mid-18th century,
though it is also sometimes written as pi.
DEFINITION OF PI(π)
The number Pi refers to a mathematical
constant. Experts define it as the ratio of
a circle’s circumference to its
diameter. The value of Pi is
approximately 3.14159 and its
appearance takes place in many
formulas in all areas of mathematics
WHO DISCOVERED PI
The representation of Pi takes place by
the Greek letter “π” since the mid-18th
century. Since Pi was discovered
by Archimedes of Syracuse , experts
also call it the Archimedes’ constant. He
was one of the best Mathematicians in
Egypt. Its appearance takes place in
many formulas in all areas of
VALUE OF PI FORMULA
In some ways, Pi (π) happens to be a really
straightforward number. The calculation of Pi
involves taking any circle and doing the division of its
circumference by its diameter. Therefore, π =
Pi (π) is the first number one learns about at school
where one can’t write it as an exact decimal.
Furthermore, there is a certain mystery behind this
number which has digits which go on forever and it
has made people curious for thousands of years.
The infinite value of Pi will be
3.141592653589…… So, when one begins to
write this number, the finishing point will never
come. The value of Pi will go on forever with
no repeating pattern to its digits.
IMPORTANT OF PI
Pi (π) is a very important and useful number. Its
appearance takes place everywhere in mathematics.
Furthermore, it has countless uses in Science and
Lots of things in this world are Pi (π) is a very important

Measurement of Circles and Value of
The most obvious way to calculate Pi (π) involves
taking the most perfect circle and then measuring its
circumference and diameter in order to work out the
value of Pi (π). This is how ancient civilizations used
to measure and this is how they realized that there is
a constant ratio in every circle.
Accuracy is certainly a problem associated with this
method. The main question is trusting the tape
measure to deliver Pi (π) correct to 10 or more
Polygons for Approximating the Value
The Greek mathematician Archimedes came up with
a method for finding out an approximation of Pi (π).
He initiated by drawing a regular hexagon inside a
circle and afterward circumscribing another regular
hexagon that was outside that circle.
This way, he was successful in calculating the exact
diameters and circumferences of the hexagons.
Hence, he was able to obtain a rough approximation
of Pi (π) by doing the division of the circumference
by the diameter.
Archimedes had found a way to double the number
of sides belonging to his hexagons. He was able to
find a more accurate approximation of Pi (π) by using
polygons that had more sides and which were closer
to the circle. He performed this to a total of four times
until he was using ninety-six sided polygons.
Archimedes performed an exact calculation of
circumference and diameter. Therefore, he could
approximate Pi (π) to be between the fraction 223/71
and fraction 22/7. The fraction 22/7 has certainly
been the most famous approximation of Pi (π) ever
Roughly 600 years since Archimedes, a Chinese
mathematician by the name of Zu Chongzhi made
use of a similar method to inscribe a regular polygon
with 12,288 sides. The result was the production of
an approximation of Pi (π) as 355/113. This happens
to be correct to six decimal places.
