computer vs calculator

Figuring the diagonal of the run and rise,w/computer:
C11 = 9", the rise
K14 = 9 1/2" the run
O14 = 11 1/4" the diagonal
on a calculator with the same input the diagonal
= 13 1/16" any ideas what i'm doing wrong
Thanks,Jim

Jim, what is the calculation for "the diagonal of the run"?

=(rise^2+run^2)^.5
...produces 13.0862523283024 or 13 1/16

See Pythagorean theorem
C^2=A^2+B^2

Mark, I've got to ask....
How did you know this???

C11 = 9"
C9 = C11/12", Ans. =(0.7500)
H9 = 12"
E9 = Sqrt(C11^2+H9^2)/12", Ans. =(1.2500)
C2 = Sqrt(C11^2+H9^2)/12"*C11, Ans. = 11 1/4"

Re: Mark, I've got to ask....
Geometry... I loved it!

You've gone too far! All you need is...
=SQRT(rise^2+run^2)

Yeah, it's only fair. We should use metric if
you buy McDonald's 113.398077437203 "gram-er".
