To find the approximate value of \(\pi\), take the wire of length 11 cm, 22 cm and 33 cm each.

Make a circle from the wire.

Measure the diameter and complete the following table.

**Circle No.** | **Circumference (c)** | **Diameter(d)** | **Ratio of (c) to (d)** |

i. | 11 cm | | |

ii. | 22 cm | | |

iii. | 33 cm | | |

Verify that the ratio of circumference to the diameter of a circle is approximately \(\sqrt[22]{7}\).
