#

in what context do you want to calculate pi ? @undone badge

#

or just for fun

undone badge Oct 29, 2023, 12:52 PM

#

Ik its C/D but is there any easier way?

#

#

it's not easy, but there's nothing easier as far as i know

undone badge Oct 29, 2023, 1:03 PM

#

Thanks

#

And by the way can you give me a perfect circle example?

dense garden Oct 29, 2023, 1:04 PM

#

i don't understand

#

oh like in real world

undone badge Oct 29, 2023, 1:05 PM

#

No, I want the values of a perfect circle.

dense garden Oct 29, 2023, 1:05 PM

#

then i don't understand

undone badge Oct 29, 2023, 1:07 PM

#

Diameter, circumference and area.

#

@dense garden ?

#

Can you give me a diameter, a circumference and an area for a circle?

desert mango Oct 29, 2023, 1:40 PM

#

diameter: 2
circumference: 2pi
area: pi

undone badge Oct 29, 2023, 1:41 PM

#

Can you give circumference as a regular number?

Reugular

#

Regular*

desert mango Oct 29, 2023, 1:44 PM

#

wdym regular number

undone badge Oct 29, 2023, 1:46 PM

#

Just a normal number 1, 2, 3, 4 etc.

desert mango Oct 29, 2023, 1:47 PM

#

a natural number?

#

you cant because pi is irrational

#

its impossible

undone badge Oct 29, 2023, 1:48 PM

#

How an I calculate pi then

#

using C/D formula?

desert mango Oct 29, 2023, 1:49 PM

#

seeing that you're in pre-uni and so i am

#

we can't

#

its complicated and you cant just draw a massive cirlcle

#

and just measure the c and d

undone badge Oct 29, 2023, 1:52 PM

#

Isn't it a paradox?

desert mango Oct 29, 2023, 1:53 PM

#

why would it be

undone badge Oct 29, 2023, 1:53 PM

#

I have to calculate pi to calculate the circumference and to calculate pi I need to calculate the circumference.

#

And it doesn't work on paper but it works on real life.

Calculating Pi (π)

Pi is central to mathematics. Calculating pi can be achieved by different methods. Ancient and modern methods can be used to calculate PI

#

I read that.

#

It says the same thing: C/D.

Using Polygons to approximate Pi (π)

#

Calculating Pi (π) using infinite series

2 ways without c/d

dense garden

How does this work then?

desert mango Oct 29, 2023, 1:57 PM

#

im not sure

#

we're both in pre-uni we dont know this stuff

@dense garden Can you explain it?

vestal agate 22/7

It is 3.142...

desert mango Oct 29, 2023, 2:04 PM

#

its close

#

you cant find the true value of pi

#

no one can

#

there are infinite digits and they never repeat

#

all you can do it approximate it

#

or use an infinite series

undone badge Oct 29, 2023, 2:05 PM

#

But nothing can be infinite.

#

It has an end.

#

I know it.

desert mango Oct 29, 2023, 2:06 PM

#

ok man

n = infinite n - 1 = infinite minus 1, n.2 = nn = n.n

desert mango Oct 29, 2023, 2:18 PM

#

idk what you mean

empty plume Oct 29, 2023, 2:34 PM

#

Pi is an irrational number cos its infinite tho

desert mango Oct 29, 2023, 2:36 PM

exactly
