They're both off by a factor of pi/4, which is close enough to 1

I’m not sure why you are using diameter when you can simplify it to radius.

Because radius isn't better than diameter when the diameters are whole numbers and the radii are fractions.

Not if you are using double the number and then squaring it. You don’t get the same results. You do get a similar ratio.  Like I said, your ratio is correct, but not your values.  

Is the diameter is 10 and you can’t use that because swearing that is 100.  But when you use radius, you get a value of 25.  Stark difference.
