Answer 1

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

Step-by-step explanation:

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

22 /11 = 2       7 /3.5  = 2

33/11  = 3        10.5/3.5  = 3

33/22 = 3/2     10.5/7.5  = 3/2

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