Question

the ratio of circumference to the diameter of a circle c/d is represented by π. but we say that π is an irrational number. why?​

Answer 1

Answer:

π is irrational

Step-by-step explanation:

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 realize 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.
