Question

Is pie a rational number? Justify your answer.

Answer 1

No,pie is not a rational no because the actual value of a pie is 3.14...........it's non termination non repetation decimal . 22/7is the estimate value of pie..

Answer 2

Answer:

Pie $(\pi)$ is an irrational number.

Solution:

$\pi$, that we use in day to day mathematics, is a fraction, $\frac {22}{7}$ which is rational.  

Often, it is considered as irrational because it is a favourite approximation for many people.

But, 22/7 is a rational number which is generally used to approximate the value of $\pi$, which is an irrational number and therefore the expression of $\pi$ as a ratio of two integer numbers is quite inappropriate.

The value of

$\pi , \frac { 22 } { 7 } = 3 . \overline { 142857 }$

22/7 is just a value for estimation of pi value. So, pi $(\pi)$ is an irrational number.
