well the reason I was asking is because I found this interesting I have not look over all of Rpenners math so this may not even mean anything so just try and make sense of it for me I remember Rpenner said circles with different diameters or not similar so there might be no connection but if there is let me know Rpenner. ok here goes if Pi * r^2 = X then r*180=Y then X=Y then X= a squares area... Y= a circles area
This is true for both the natural circle of radius 180/pi and this circle of different diameter and different C/d ratio ...180/3.125
so 180/3.125 =r then 57.6 *180 = 10368 then 3.125 * 57.6^2 =10368= circle one
now 180/pi =r then r*180 = 10313 approximately then pi *180/pi= 10313 approximately =circle two

this is not true far any other number combinations unless I was mistaking??

and also for further clarification

360/115.2 = 3.125 ...and 360/180/pi *2 =pi and
3.125 * 115.2 = 360 ...and pi * 360/pi= 360

I once saw a proposal that made a lot of sense to me. Once we accept that we can never really use the exact value of pi in any practical manner (i.e. in the "real world") then perhaps we should list it with a subscript indicating the significant digits used in any given (e.g. manufacturing) calculation. $\pi_4 \pi_8 \pi_{200}$, etc.

It's an equation with one uknown: it doesn't mean anything. It is just a cumbersome way of defining a value for r. You could make an infinite number of different relations, all equally meaningless. For example:
r*360=pi*r^4
r*2.5=pi*r

They don't mean anything at all.
No, Pi*r^2 does not describe a square, much less say anything about it "increasing" (whatever that even means).
No, the area of a circle is pi*r^2. Without squaring the radius, you don't end up with units of area. What you did there doesn't make any sense.
No.
I think you meant to say that X is the circle's area, and Y is the square's area, but r*180 doesn't have units of area, so it can't be a square's area.

And even if you intended 180 to be in units of area (inches, meters, whatever), 180*(180/pi) is two different lengths, so it isn't a square!

I'm sorry, but it looks like you are just throwing random numbers and letters together without much of an understanding of what they mean or how they actually fit together. I really think you should take a step back and acutally learn some math. I'm sure there are local community colleges that offer adult education courses in remedial math and it would help you a lot to understand this stuff better rather than just throwing random gibberish together and wondering if it means anything.

Remedial posting would be in order as well..

Hence the saying "pi r squared" definitions or describing something tangible they are not just meaningless words as how you would put it it would not be called a square if it was not a square common sense...

Instead you stand idly by in your mockery explain what is correct and tips on how to post correctly?

No, r^2 is a number squared. It isn't, itself, a square. If you like, it can be considered the equatio for the area of a square, where "r" is the length of a side.
No. The area of a square is a=r^2 where "r" is equal to the length of a side. But a=180*r^2 is meaningless. It is just 180 times the area of the square.
I do: it doesn't.
A degree is a unit of angle. 180/pi is not.
It isn't that either.
In e=mv^2, what is the square?

I do not like repeating myself its a luxury right now I don't have time for, if you cant visualize the mathematical concept am talking about I apologize I don't have time to fill in the blanks that's why I prefer to talk with Rpenner because he gets it quick and I will not respond to something he says until I can fully analise every detail in full accurate comprehension of what his math is telling me if something is not clear to me I will not just assume a conclusion. This is the wrong time to play a game of semantics with me.

Lol, none of what I was explaining to you had anything to do with semantics and it wasn't a game. I was honestly trying to help you. Sorry, but you are severly lacking in math skills. I truly wish you luck in fixing that because this is the sort of misguided obsession that consumes peoples lives. Just ask Farsight! Unless there is somethign else going on, in which case math help may not be the right kind for you.

Only value your presence of existence can have to me is if you can get Rpenner to respond to my calculations other than that am sure you will be happy as to act as if I don't exist for that I assume will be mutually beneficial in other words don't talk to me unless you can bring Rpenner I do not value your opinion.

Blah, blah, blah. Not sure who you think you are, but this is an open forum. If you want a private chat with Rpenner, PM him.

Then don't respond! I don't see a lot of sense in what you are posting myself. Feel free to not respond to me either.

Tan (pi/4) is not equal 1 when pi = 3.125 it's equal to less than one

2 fractions is not a contradiction contrary to lamberts proof no integers and
Aproximately value 7.96/2.21 =3.60181

Pi only appears to be rational because 8/2.22 = 3.60360
This is why Tan(pi/4) = 1

Sorry if this makes no sense to anyone my math is sloppy I leave a lot of gaps because am lazy ask Rpenner if he could explain it better...I am a conceptual mathematician I just like communicating concepts like an artist you have to read between the lines and put it in your own words...

r=1
pi=3.14159

1*360=3.14159*1
1*2.5=3.14159*1

That's what you claim?

d=7.4
r=3.7
pi=3.14159

Circumference=pi(r2)=pi(d)
Area=pi(r^2)

No. When presented with an equation that has one unknown, you don't insert a random value for the variable, you solve the equation to find the value of the variable. You should take some remedial math too.
