A (rational) estimate for æ also provides an estimate for, since if 0 < a < b, then 1/b < 1/a (a) Use the estimate 330/106 < π < 355/113 to find a range containing . (b) Both your lower and upper bounds should be in the form of fractions. Use long division to determine the first six decimal digits of each. Show your work. (c) What does this tell us about the decimal expansion of 1/π ?
