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?
100*pi≈314 feet
How do you find the square feet of a circle with a radius of 10 feet?
314 feet²Area of a circle = pi x radius²let pi = 3.14A = 3.14 x 10²A = 3.14 x 100A = 314 feet²
What is the area of a circle with the circumference of 62.8 inches?
Circumference = 2 pi r = 62.8 so r = 31.4/pi = 10 Area = pi r2 = 100 pi = 314 in2

pi is irrational so that's impossible
How can we prove that when a circle's diameter is 1 its circumference is pi?
Because the circumference of a circle = pi*diameter and pi*1 = pi
