Question

4
4. The ratio of circumference to the diameter of a circle is represented by a . But we say
d
that a is an irrational number. Why?​

Answer 1

Answer:

Step-by-step explanation:

An irrational number is one that never terminates and never repeats. So, when you divide any circumference by its diameter, you will always get π.

$\pi =\frac{C}{D}$

​       is a rational number  

When c & d both are rational numbers

But the c & d we calculated is not exactly a rational number and either c or d or both can be irrational numbers

Since quotient of rational and irrational number is an irrational number .

So π is an irrational number
