project on pi for class 9
Answers
Answer:
THEORY
Irrational numbers are those numbers which cannot be expressed in the form of pq , where p and q are integers and q ≠ 0. e.g. √2, √3, √5, √7, etc.
The number π (pi) is an irrational number, which means that its value cannot be expressed in the form of pq, where p and q are integers and q ≠ 0.
It is also a transcendental number, i.e. no finite sequence of algebraic operations on integers.
The constant π is the first Greek letter, which is used to find the circumference or perimeter of a circle.
The number π is the ratio of the circumference of a circle to its diameter.
i. e. π = cd , where c is the circumference of a circle and d is the diameter of a circle.

The first scientist Archimedes Syracure (287 BC) gave the first theoretical calculated value of pi (π).
Step-by-step explanation:
CONCLUSION
Here, we conclude that generally the value of π is used as 227 or 3.141 in different areas of field.
APPLICATION
The value of π is used in finding areas and perimeters of designs related to circles and sector of circles. It has applications in the construction of racetracks and engineering equipments.CONCLUSION
