$\pi \: is \: a \\ (a) \: a \: rational \: number \: (b) \: an \: irrational \: number \: (c) \: a \: natural \: number \: (d) \: none \: of \: these$
​

Answer 1

Answer:

• π is an irrational number because it cannot be expressed in the form of p/q (fraction ).

• So, the required option is (b) rational number .

Extrac Information :

➻ The number which can be expressed in the form of p/q where p & q are integers and q≠0 . It is called rational number .

For Example

• 2/7 , -6/7 and 9/6 etc.

➻ The number which cannot be expressed in the form of p/q are called irrational number .

For example

• √5 , π and √6 etc.

Answer 2

Required Answer :-

π is an Irrational number

${\huge{\boxed{\bf{Why \;?}}}}$

Because π cannot be represented as a fraction. And we know that rational number are those number which can be represented as fraction form. So, Option a is wrong. π is also not a natural number
