Question

The ratio of circumference to the diameter of a circle c/d is represented by p . But we say that p is an irrational number. Why?

Answer 1

Mistake in the question : represented by pi(π). say that pi(π) is an irrational number.

SOLUTION:

Circumference = π × diameter

c = πd

π = c/d

π is the ratio of the circumference of a circle to the length of the diameter.When we measure the length with the scale Or any other device we only get an approximate rational value so we may not realise that in c & d which one is irrational.So either c or d is irrational and hence c/d is irrational i.e π is irrational. Hence ,there is no contradiction in saying that π is irrational.

Answer 2

Step-by-step explanation:

cicumfrence=π×daimeter

C=πd

is the ratio of the circumference of a circle of the length of the daimeter . when we measure the length with the scale or any other device we only

get an approximate rational value so we may not realise that in C and D which one is irrational .So either C or D is irrational and hence C/D is irrational . i.eπ is irrational.Hence there is no condtradicition in saying that is irrational.
