@anneska,
don't round pi in LC except if you are specifically told to do so.
And you missed something important in the question. And try not to provide full answers, people are usually touchy about that, if you want to discuss about your whole theory try to PM someone you think knows what he is doing.
@krazykatana,
cant believe I forgot to times the pets by 3!

sorry
@anneska,
Um, at least 2 errors in that calculation, anneska. And then the whole pizza issue means that buying all of them in the cheaper version doesn't necessarily give the lowest cost.
@edstock,
true, in this case (with the data he used) it would be cheaper to buy 7 small and 1 big
Ok, I solved the problem after just using guessing and checking.
Good luck to everyone else!
@krazykatana,
O man, looking at your post again I found way more things wrong, forget about the 7 small/ 1 big, I count at least 4 errors.
@anneska,
Anneska, there are a few things wrong with your calculation. Try googling how to find the area of a circle, and make sure you fully read the question your missing a key component.
@omgzarrr,
yeah basically,
value of pi is wrong, nps/sq inch is wrong, area formula is wrong, number of guests is wrong and assuming the correct answer is only made of the cheapest pizza is also wrong.
i got a 5 digit number starting with a 2 anybody else get the same?
lets just assume that the total area needed of pizza is 11340. would you have to fill that with pizza sizes with as many/as little needed for the lowest cost? also, did you get whole numbers as the areas of the pizzas?
@tutors,
also, to get the area of a circle, would you need the radius x pi?
also, would the total area become a digit number or would you keep it a whole?
@tutors,
this is quite frustrating!
@tutors,
the area of a circle is pi x radius^2(squared).
uggghhh i made the same mistake as at least 1 other.... so simple too, but i had the wrong number of guests. did all the other math right though, and no excel spreadsheets, linear equations, anything like that.... it really is simple basic geometry (area of a circle) and then just calculating the cheapest per square inch, etc. Don't wanna give too much away, but yeah just venting cuz this was such an easy puzzle, and I made such a stupid mistake. Good luck to the rest of you.
oh and i haven't been in school in like almost 10 years, and I still remember this. Considering most of yas are still in hs.
