Answer:
Step-by-step explanation:
If we consider a circle with a diameter of 7 cm... by superimposing a thread we may find that the circumference is approx. 22 cm.
Now, as we know that
2 pi r = c
d * pi =c
pi = c/d
Hence by dividing 22 by 7, we get 3.14 to two decimal places
[Note: The exact value of pi can never be found... as it is irrational. But for simplicity.. we take it as 3.14]
