If
the area of circle A is 3 times the area of circle B
and
the area of square WXYZ is 6 times the area of circle B
then
the area of square WXYZ is 2 times the area of circle A
We know
the area of square WXYZ is 4/ times the area of circle in square WXYZ
So required ratio = 2*(/4) = /2

LOL... when he becomes uberpuzzler I will be totally depressed... I have yet to come across anything he hasn't answered with complete bogus. Really srn347, would it be too much to ask for you to show a bit of maturity? Though I may be asking too much from someone who is probably no more than 15 at the most...
By the way Mike, nice avatar!

Thanks  , srn347 is 13. Still, in certain religions like Judaism, he would be considered an adult, yet he has never shown it. It amazes me that he thinks he can cope with complex problems and ideas way over the top of his head, most of the time it is over mine aswell. It seems he has very selective hearing/reading. He doesn't even read problems, answers them and then runs away when confronted with insults and complaints.

He will never be an uberpuzzler in the way that I meant it. I won't deserve the title if I make that many posts, I just like to enjoy myself not post for the title. I did at one stage, but I have calmed down now.

You will become an uberpuzzler (by the rules of this forum) in a while, hardly 2 months after you joined it.

Yes, but I don't deserve the title, rank maybe, but title no. I am not an uberpuzzler, If I were, well we can only imagine the possibilities. By this I mean, that 5 stars, maybe, being called an uberpuzzler, not at the moment.
Look at flamingdragon. He was averaging 40 posts every 12 hours, he went from 150~ - 650+ in a few weeks if that.

And Iceman, whose posts often consist of of only one syllable, yes and no.
Still, at least he contributes many WTF? type puzzles.
But I think I am still the numero uno puzzle poster. 
In terms of amount of lines posted [and helpfulness of posts], I would say that Icarus is #1, probably followed by towr.

And I would agree with you there. Although since Icarus has been away for several months now, I would bump you up to #2. If he ever returns (let's all hope he does), I would have to move you down.

Equal second with Grimbal then. I mean, at least he has cool pictures everytime the page refreshes.

I don't know how mikedagr8 knows, but it makes sense with his math level he just told me was advanced algebra (the equivalent of the U.S. Algebra 2) which would be possible if he was taking honors courses, etc (which would explain the over-confident, cocky attitude...)

It's one of the 24 pages. It amazes me he says now that he can use divsion, yet in the original page he says we cant divide.
Quote:| 3/7 involves decimal points which are forbidden. Exponents and sqrts aren't useable either. How about (3-3)/(7-7) or vice-verca. 0/0 is anything so it could be 24. |

This guy really is a character. Remember, according to a 13 year old, who says he has done calculus, 0/0 is 24. I mean, I don't start learning calculus for another year, but he has already learnt it, probably mastered it to his standards as well.

Really?  Actually Mike I would have figured you had already started it... in fact you probably are already much closer than you think... at least in all the courses I had, you were learning the concepts and building the foundation ahead of time, they just didn't tell you as such. Then when you got to calculus they just went "suprise! now here is how to use it..." But you'll probably like it... it just makes so much sense you wonder why everyone gives it such a stigma. Good luck!

YES, THAT'S EXACTLY WHAT IS HAPPENING!!!
Next topic we start derivatives....CALCULUS WOOOOH! We're doing circular functions, then on to 'rates of change' and 'differentiation of polynomials'!!!

Wait how can you start on derivatives without limits? Btw what is the thread about?

Rates of change has a sub-chapter I suppose you would call it, with limits as a topic. It's a jumbled book, and the teacher teaches in his own methods so I guess we will see. This thread was just a general conversation/topic. I'm not 100% sure anymore
