I just used 3.1416. I knew that far from memory. You probably went out some more digits for pi.

On a different tangent, did you know the banker refused to give the mathematician a car loan?

All the formulas were filled out correctly, but it seems he couldn't get a cosign, and then the errors multipied.

Excel has a function called pi(). You just insert it inside the sqrt function:

sqrt(pi())

Then do a Format | Cell | Number and give it 14 decimal places. If you try to give it more than 14, you just get zeros in the decimal places after the 14th.
