Question

find the value of pi taking average of the ratios of circumference and diameter of atleast five circle of different radii experimentally​

Answer 1

Ratio of  circumference to the diameter of a circle  = 22/7

Step-by-step explanation:

Take a  wire of length as mentioned below ,

make a circle  & measure  Diameter

S. No.        Circumference                  Diameter          Ratio  

1                  11                                       3.5 cm              22/7

2                 22                                     7 cm                 22/7

3                 33                                     10.5 cm             22/7

4                 44                                      14 cm                22/7

4                 55                                      17.5 cm             22/7

Ratio of  circumference to the diameter of a circle  = 22/7

π = 22/7
