Question

Pi can be written as circumference/diameter for a circle. But pi is irrational, then how can it be represented in the form of a rational number(c/d)?

Answer 1

3.14

Answer 2

22/7 is the approximate form of pi.

Answer 3

But that isn't my question.

Answer 4

22/7 is not the exact value of pi.

Answer 5

If pi is irrational, then how can circumference/diameter be pi because c/d should be rational.

Answer 6

22 / 7 = 3.14285714

Exact value of pi is = 3.14159265

Answer 7

@pratu043 No, we can't say that.

Answer 8

what do you mean?

Answer 9

It's not necessary that when two rational numbers are divided, we'll get a rational number.

Answer 10

Can you give an example?

Answer 11

An example is pi :P

Answer 12

But 22/7 is rational. If you divide, you'll get a recurring decimal.

Answer 13

Definition of a rational number is that it can be expressed in the form of the division of two INTEGERS.

Answer 14

22/7 is not pi.

Answer 15

22/7 is the approximate value of pi.

Answer 16

OK, first pi is irrational right?

Answer 17

Yes.

Answer 18

@ParthKohli are you there?

Answer 19

Yes, I am

Answer 20

Pi can be written as circumference/diameter. But pi is irrational, then how can it be represented in the form of a rational number?

Answer 21

You're not getting the point.

Answer 22

Circumference and diameter. Both have to be integers, but they can't be.

Answer 23

Circumference and diameter of a circle are integers right?

Answer 24

Or at least in some cases.

Answer 25

No. They can't be at the same time. never.

Answer 26

So, circumference and diameter of a circle are never both integers?

Answer 27

Yes.

Answer 28

Let me guess .... its because we take pi as 22/7?

Answer 29

Am I right?

Answer 30

Theyre taken as 22/7 or 3.14 for simplicity :)

Answer 31

Thanks!!!
