I'm not sure of the proof. Wikipedia has an extensive article on pi, it's history and calculation methods. Pi is the ratio of a circle's circumference to its diameter. It is an irrational number, so it cannot be represented exactly as a decimal or a fraction, but only carried out to a decimal approximation.

The decimal 3.14 is a pretty good approximation to the true value. If you take a circle with a diameter of 100 yards (the length of a football field), then calculate the circumference using the approximation of 3.14, you will be off from the actual length of the circumference by about 5 3/4 inches. Using another popular approximation [22/7] will get you within 4 9/16 inch of the actual circumference. Using the popular approximation of 3.1416 will arrive at a calculation which is within 1/32 inch of the actual circumference.

Circumference of a circle with a diameter of 100 feet?

The circumference of a circle can be calculated using the formula C = πd, where C is the circumference, π is a constant approximately equal to 3.14159, and d is the diameter of the circle. In this case, the diameter is 100 feet, so the circumference would be C = π(100) = 314.159 feet.
