Recall,π is defined as the ratio of the circumference (say c) of a circle to its diameter (say d) .that is π = c/d .this seems to contradict the fact that π is irrational .How will you resolve this contradiction?
plz answer the question​

Answer

When we measure a length with a scale or any other device, we only get an approximate rational value.  

Therefore we may not realise that c or d is irrational.

Circumference c or the perimeter of a circle is given by 2πr,

where r is the radius of the circle

π is approximated as 3.14 or  

7

22

​  

 

Also diameter(longest chord of circle) of the circle is equal to 2r.

Hence, c=(2πr),d=2r⇒  

d

c

​  

This is analogous to the approximated value of  

7

22

​  

 which though looks like a rational number of the form  

q

p

​  

 (q!=0)
