@Unitynow8,
Yeah thats what Im thinking too. I think I figured out that to make 16 revolutions of the string, you would have to use 144 cm of string per revolution. That is rounded up.
@Unitynow8,
I've figured out the distance between each loop, but I'm lost since I don't know how tightly the string is wound. If it is the tightest possible, then we need to know the string thickness, but if it isnt tight then I dont know how to go on.
i agree with unity -- we need to figure out the Length of the pipe covered by a wrap... and it's NOT wrapped tightly.
this can be seen from: total rope length (2300) / # wraps (16) = 143.75. cm
so, that's how much rope is used per twist.
IFF it was wound tightly, one wrap would only take the circ = D*pi = 40.84cm
so it's obviously a loose wrap ... but how to figure out the related distance of pipe is alluding me.
@K311Y,
ok... But isn't pi a number that has an infinite amount of digits?
@Jen Aside,
I'm thinking the same thing, but I'm not a math wiz. For instance, a string that is 1/4 inch thick and goes around the cylinder 16 times would not go as high as one that is 1/2 inch thick. Or am I missing something in this LC question?
@jjbuttcrack,
Yes, I agree that the string would have to be wrapped loosely, otherwise it wouldn't reach the bottom of the pole
i believe the string is coiled around the cylinder kinda of like the problem on this page :http://mathforum.org/library/drmath/view/55156.html
I don't believe that there is enough information provided to solve. Is there any chance that the answer has something to do with the Chocolate Factory?
the string has a thinkness, but it's not shown. We don't know if the string is tightly coiled around the pole or not
@warhammer11,
lol i was looking at that too.
@starleogirl09,
hmm? it could be a wide string, but thin! |==============================| It can be a short pole!

@Leopard,
we should presumed it is coiled tightly and the string does not have a thickness because the info is not provided
@Leopard,
Most likely it isn't, but I'm not positive
But looking at the length of the string and knowing that it goes around only 16 times we kinda can figure out the height of the pole. Because a short pole would not have a 2300 cm string go around it 16 times, because the sting would be to long. And with a long pole a 2300 cm would be too short to go around 16 times
hmm.... i like it, warhammer .... but i think this solution is considering a tight wrap (ie coil), since the ends of each loop lies right on the hypotenuse of the triangle. ... umm... this is on the right track though. we just need a similiar solution for a loose wrap..... perhaps i'll look a little closer at the equations and see if there is something i can tweak. but as it is, i don't think this will give a correct answer.
@Leopard,
so it is a medium legth pole
I think all the infomation is given to solve the answer
Try imagining it. A pole, and a string around it. Wrap the string around the pole and make sure it goes around 16 times, And the string has to be exactly 2300 cm long.
