Answer» Explanation: 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 =π This is analogous to the approximated value of 7 22 which though looks like a rational number of the form q p (q!=0) But when computed corresponds to a real value of ~3.14. And real numbers consists of irrational numbers. Hence, there is no contradiction in the equation = d c .

Answer»

Explanation:

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

Also DIAMETER(longest CHORD of circle) of the circle is equal to 2r.

Hence, c=(2πr),d=2r⇒

=π

This is analogous to the approximated value of

which though looks like a rational number of the form

(q!=0)

But when computed corresponds to a real value of ~3.14.

And real numbers consists of irrational numbers.

Hence, there is no contradiction in the equation =
