Ah, yes.

There were those who claimed that pi is

3.14159 26535 89793...

but that rule, according to others, fails to 'work both ways
mathematically', and thus one instead needs to recognize that "the
ratio of the chord and arc of ninety degrees is as seven to eight".

Thus, pi is actually equal to 32 divided by seven times the square
root of two, which would be

3.23248 81425 67074...

except that the commonly accepted value of the square root of two is
wrong too, as "the ratio of the diagonal and one side of a square" "is
as ten to seven".

Which makes pi equal to 3.2, as "the ratio of the diameter and the
circumference is as five-fourths to four".

Of course, if you put four squares next to each other to make a bigger
square, then their diagonals form a square too. And the side of that
square would be ten, while the diagonal would be fourteen; and
fourteen to ten is not quite the same as ten to seven. So, indeed, it
is the rule of Dr. Edwin Goodwin that fails to work both ways.

Isn't pi exactly equal to 3 according to some old US law from the 1800's ???
