At one level a huge deal. Pi is known to an accuracy of the width of a hydrogen atom at the far end of the known universe.
At the same time, since pi is an irrational number, it has an infinitely long decimal representation with no recurrence. So even if we knew 1 quadrillion digits of pi (we don't yet) we would only know one quadriliion infinitieth (to coin a word) of pi - that is 0%.

The digits of pi are known to more than a trillion (1012) digits, but it is impossible to state all of them in this forum.
Aryabhatta did not discover pi - it was known long before him. He found a more accurate value and a method for calculating pi to greater accuracy than was previously known.
Circumference of a circle = 2*pi*radius or pi*diameter
The number pi can be defined as: pi = circumference / diameter. Solving for diameter: diameter = circumference / pi. Pi is approximately 3.14.
The decimal representation of pi, as of late 2011, is over 10 trillion (1013) digits.
The longest known value of pi is now into the hundreds of billions of digits.
No. pi was known long before.

Consider a distribution with an unknown parameter pi. If the true value of pi is not known but has been estimated, then the estimated value is usually denoted by pi-hat. This is to distinguish between a known parameter and an estimated one.

3.14159265">the number pi is equal to is 3.14159265
Diameter = circumference/pi where pi is 3.14159 (approx)

Though pi lasts forever and cannot fully be written out, pi is commonly known for its first three numbers: 3.14 pi = about 22/7 pi = 3.1415926535897938.........and so on
No, pi has no known ending, or any repetitious sequences of numbers for that matter.
