Practice and memorization. It may help to memorize the digits in sets, like ten at a time. Here are the first 50 digits if you want to work on memorizing them: 3.141592653 5897932384 6264338327 9502884197 1693993751
You need just a smidgen of algebra.The area of any circle is (pi) x (radius)2 .For this circle, you know that (pi) x (radius)2 = 49.You can massgae this around to find the radius, and thenthe circumference is just (2 pi) x (radius).If you need it all in one step, then Circumference= 2 x sqrt(pi x Area) ,but the other way is easier for me, because I don't have to memorizeanother formula. I find deriving easier than memorizing..

You could try memorizing the first 100 digits of pi. 3.1415926535 8979323846 2643383279 5028841971 6939937510 5820974944 5923078164 0628620899 8628034825 3421170679
just remember it by 3.14 The best way to remember pi is by memorizing the sentence: "How I wish I could determine of circle round the exact relation Archimede found" The number of letters in each word of this sentence represents one figure of pi. Only the last figure (5) from the word "found" does not correspond to the correct figure of pi in its position.
yes pi is used around the world today
All around the world, because pi is used in many formulas.
