...Do you seriously need it to fourteen significant digits?

Distance from D to A => Diameter of the biggest, since it's a straight line that divides it in two equal sections crossing the center
Same for D to B or C, because you can translate them to divide the smallest circle.

Distance from point to point (cartesian) is sqrt((x1-x2)^2+(y1-y2)^2) by pythagorean theorem

Assuming that dot in the middle is the center the outer circle is just the distance from A to D

For the inner you can probably use the triangles to find the disance from the center to the midpoint of one of the lines on the square

Isn't it sqrt((x2-x1)^2 + (y2-y1)^2) ?

>>4799205
distance from T to S is the smaller diameter. the distance from D to A is the bigger diameter.

>>4799219
It doesn't matter, both are valid because there is no magical way to pick which is 1 and which is 2

>>4799215
I'll be using the figure in comparison to another with just about as many and I need it to be as accurate as possible.

>>4799219
since you are squaring it, it doesn't matter

(a-b)(a-b) = a^2-2ab+b^2 = (b-a)(b-a)
therefore
(a-b)^2 == (b-a)^2

>>4799205
is the X coordinate of B supposed to be different from the X coordinate of A?

Thanks for your help, folks.

Just to make sure I have this clear, I'll be using one of these equations...

...twice; once for each set?

>>4799247
yes, that would be it

>>4799240

Yeah, it's a basic representation of the Great Pyramid at Giza. The sides aren't equal in value.

>>4799253

Neat. Again, I appreciate it. Sorry for being a high-school dropout.

>>4799265

*wondering why I inserted the unnecessary hyphen in high school*

Oh right, because I'm a dropout. Of course.

The difference between the diameters of the inner and outer circles seems to be 1.821122311

amidoinitrite?

Just realized that I'm not. Go about your business.

The numbers are not correct.
A circle can be defined by any 3 points on its circumference.
The outer circle contains the four points:
A(4.3967,4.3993)
B(4.4005,0)
C(0,4.3987)
D(0,0)
Upon programming the circumcenter equation, I found that the parameters ABD and ABC produced a centre of (2.20050,2.19775). BCD however yielded (2.20025,2.19935). ACD yielded (2.19865,2.19935).
Something isn't right here. I'm highly doubting that it's a precision error.

>>4799441
this man is correct. At least one of those points on the outside big circle is wrong.

We must recall the masonic secret of squaring the circle. This has a lot to do with harmonic levels of human consciousness

>>4799506
Is there like an archive of math crackpottery?

It would make for excellent troll copypasta

So does anyone have the correct numbers on the Great Pyramid, then?

Fuck it i'm posting the pages

I'm not the guy you're replying to, but the reason I made this thread is because I was attempting to validate the claim that the outer circle's circumfrence minus the inner circle's would result in 299.79 [meters, I believe] which is quite close to the speed of light [299792458 m/s]. The number I used in the OP were in cubits and the circles were only approximations, as the dimensions weren't *square* as it were.

I did calculate another set of figures as well and the result is around 1.822. This is obviously not in any way similar to the original claim I ran across.

what do you make of it?

299792458 m/s... 29.9792458°N, 31°8'3.11"E

Google it.

I'm trying to find ebooks right now, actually.

those cannot be circles, and DCAB is not a square, with the values given. They are ellipses. More specifically, CDB is a right angle, but none of the others are. The difference is slight, but it's there.

You can't find the diameter of the circles because they are not circles and the diameter is going to be different based on at which angle you measure it.

If I were in your shoes I would assume CA is at Y=4.4 and AB is at X=4.4, making the diameter of the outer circle the square root of (2*4.4^2), and the diameter of the inner circle that times the square root of two over two.
