Required
Select matching pairs
Represent diameter with D and Circumference with C
C is calculated as:

Where

A. D = 5m; C = 22m
Using: 


15.71 does not approximates to 22m.
Hence, the pair do not match
B. D = 19 in; C = 60 in
Using: 


59.698 approximates to 60.
Hence, the pair match
C. D = 33 cm; D = 80 cm.
Using: 


103.686 does not approximates to 22m.
Hence, the pair do not match
<em>From the analysis above, only option B matches the diameter with the circumference</em>
