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 \(\sqrt[22]{7}\).
