I have a square table that is 32.5" on each side. I want to put a round top on this table. so in order to know the size of the round top, I need to know the diagonal measurementof the square table. HELP.

I'm not sure I understand what you mean, but I'm pretty sure that the good old Pythagorean Theorem is the tool you need

Patrick is right. Using Pythagoras, you can work out the diagonal of the table as √(32.5²+32.5²) = 46.0".

Why did the vector cross the road?

It wanted to be normal.

thank you for the 46" measurement. I understand that it is the sq root of 32.5" sqd + 32.5" sqd, but (for future referrence) is there a formula that I can use for other such problems?? I mean how would I have found the sq root of c sqd to come up with the answer?

Hmm, let me guess, you've never used the formula have you? It should be pretty straight forward if you had..

<- this is the formula I'm talking about..If you havn't, you might wonna look a bit at this link: Mathsisfuns's explanation of the method
