WORLD CIVILIZATION

Detailed explanation-1: -Archimedes’ method finds an approximation of pi by determining the length of the perimeter of a polygon inscribed within a circle (which is less than the circumference of the circle) and the perimeter of a polygon circumscribed outside a circle (which is greater than the circumference).

Detailed explanation-2: -(The diameter is twice the radius, the length from any point on the circle to its center.) If you divide the circumference of the circle by the diameter, you will get approximately 3.14-no matter what size circle you drew!

Detailed explanation-3: -Archimedes knew that he had not found the value of but only an approximation within those limits. In this way, Archimedes showed that is between 3 1/7 and 3 10/71.

Detailed explanation-4: -Archimedes created one of the essential physics concepts that is the centre of gravity. He discovered the laws of levers and pulleys that allow moving heavy objects using small forces. Archimedes calculated the most precise value of pi.
