if the inner circle radius = 1
the circumference = 2 pi r = 2 pi ~= 6.28...
then the inner square side = 2
and inner square perimeter = 8
so rise and run would both = 1
rise x run = 1 • 1 = 1
rise / run = 1 / 1 = 1 = slope
run / rise = 1 / 1 = 1

so the outer circle radius = √2 ("root 2")
and now this circumference = 2 √2 pi ~= 8.88 5 76 58 76...
thus the outer square side = 2 √2 ~= 2.828...
and outer square perimeter = 8 √2 ~= 11.3137...
so now rise and run 2 both = √2 ~= 1.414...
rise 2 x run 2 = √2 • √2 = 2
rise 2 / run 2 = √2 / √2 = 1
run 2 / rise 2 = √2 / √2 = 1

run 1 / rise 2 = 1 / √2 = √2 / 2 ~= 0.707...
run 2 / rise 1 = √2 / 1 = √2 / 1 ~= 1.414...

problem # 50

area of a circle
with diameter = 9
A = pi r2
r = d/2 = 4.5
r2 = 4.5 • 4.5 = 20.25
pi r2 ~= 63.61725124... = area
/ 8 ~= 7.952156404... = 1 khet
/ 8 ~= 0.9940195505... = 1 setat
