Or (more for fun than any practical application) try (2143/22)^(1/4) = 3.14159265268. Other approximations I have seen are root(10) and 3.142. This last was especially popular at school, which for me was sufficiently long ago to have used four figure log tables. The Old Testament (1 Kings 7,23) says ... "And he made a molten sea, ten cubits from the one brim to the other: it was round all about, and his height was five cubits: and a line of thirty cubits did compass it round about. ". So pi=3.
