The age of the Universe is calculated based on several methods; one that is fairly easy to understand is the expansion of the Universe. If you extrapolate the expansive movement of the galaxies into the past, you get to a point where they were very close together. The time when this should have happened gives you a general idea of the age of the Universe - assuming that the speed of expansion didn't change.

39 decimal places.
pi is an irrational number and one characteristic of irrational numbers is that their decimal representation is neither terminating nor recurrent. This is also true for any other base for counting (other than pi itself). Also, pi is a transcendental number and so cannot be represented as a sum of algebraic operation on integers. Although the value of pi has been calculated to an accuracy of over a trillion digits, only 40 digits are required to calculate the circumference of the observable universe to the accuracy of the size of a hydrogen atom!
In an equation like C=2PiR, the circumference (C) of a circle in terms of the radius (R), we call the values of R to be in the Domain and the values of C are then calculated and we say those results are in the Range. So the Domain is any quantity from zero to the width of the universe if you want to be practical. I suppose that someone might like to calculate the circumference of two adjacent universes, so their Domain for R would be twice as big. Notice that the Domain contains no negative numbers. No practical circle has a negative radius.

No. It is a constant. The Greek letter pi is used to denote the following: A fundamental mathematical constant defined as the ratio of the circumference of a circle to its diameter. It is a transcendental number with the decimal expansion 3.141 592 653 589 79...More than a trillion decimal places have now been calculated; just 39 places are sufficient to compute the circumference of the observable Universe accurate to within the radius of a hydrogen atom.(According to the Penguin Dictionary of Science)

My guess is fewer than 100. But physical measurements are nothing like as accurate, so maybe 6decimal places would suffice for most measurements.
No, pi is a mathematical constant, independent of the physical world. In the case of space curvature, the formula for the circumference of a circle might no longer be completely accurate, but that doesn't affect the value of pi.
All the available evidence strongly indicates that the Universe is, indeed, expanding.
That's a fascinating question. I have an answer, but it's one that I'm not100% sure of in my own mind, so I'm going to call itAnswer #1:I think the accuracy of the value you calculate doesn't depend so much on theconversion factor you use, but more on the accuracy of the data you start with.So it makes no difference what value you use for PI, unless you start out with anumber for the radius of the observable universe that you know to be accurateto within the proton radius. If your radius isn't that accurate, then there's nothingyour proportionality factor can do to it to fix the answer. Whatever radius you startwith, if you use one more significant figure of PI than the significant figures youhave in the radius, the accuracy of the radius is preserved in the circumferenceyou calculate.That's my suspicion.
What?!! Radius cannot be measured in Newtons!
Postulated that the Earth is curved and calculated the circumference of the Earth to within 1% of accuracy, simply by using shadows and geometry; then placed the sun at the center of the then known solar system - known as the heliocentric universe.

All of the planets in this universe are different. Some of them may have a same number. I'm am very positive that all planets in the universe do not have the same Diameter or Circumference.
