hmmm
pythag only works for triangles doesnt it?
My result is 27 cm, but i don't think this is the answer. The blue line is there for a reason...

i think its 30 but "please round up to the nearest centimeter." makes me think i'm wrong sooooo if i am wrong my bad!
Line
Of course the blue line is there for a reason. It's used to check your answer. :wink:
Fine i'll show u answer... hope you can understand it. Post any questions

I just drew a circle with a perfect square, where this doesn't have to be so... just make the square nearly as big as the circle...
Sorry, but i'm terrible at maths

the image is not working for me O_o
LC
jonathanasdf the link you posted goes to a site where it says image not found
I know I know sorry technical problems...
And i suk at computer drawing sry
I'll post it again on this page
It's a bit big
sry bout double post =(
LC
A(8) squared plus B(8) squared.......... so the answers 64????

I just checked your math with a real circle and square and it's not working out. The corners of the square are nearer to the circle then the center (because the center is the point furthest apart from every point of the circle per definition). So it can not be 24 cm it has to be larger.
The side of the square is larger than red line
So Side is not 16 cm
Is use paint shop pro to count pixels and i get that red line es the 80% of the side. Sorry for my english!

the last part i just posted is wrong, just ignore it, it's way too late for this, but it's not working out anyway.

That's what the parallel lines are for.
no
that's wrong because if you look closely, you'll see that the red line starts higher up than the blue, therefore 24 is not the wright answer.
Hmm.. I see your agruments... I'll try to do it wiht math this time...
But if the case is that the red line is longer than blue, because we are not sure that the image by TNT is drawn to scale, if the square is bigger than it appears, the red line will be longer, while if the square is smaller, the red line will be shorter. Also there is rounding, so a little bit more will result in either 24 or 25. Just guess one...
