- π is the ratio of the circumference of a circle to its diameter, which is a constant.
- π is an irrational number. In decimal system, its value is approximately 3.1415...
Solution:
π ≈ 3.1415...
\(\rm \dfrac{22}{7}= 3.\overline {142857}\)
\(\rm \dfrac{7}{22}= 0.3\overline {18}\)
\(\rm \dfrac{1}{22}= 0.0\overline {45}\)
\(\rm \dfrac{22}{3}= 7.\overline {3}\)
∴ \(\rm \pi \approx \dfrac {22}7\).
