A fool
wants to tie a rope around the earth. So he buys a rope of 40,000 KM and ties it around the world. His neighbour, also a
fool, wants to do the same only he wants the rope on sticks 1 meter above the ground.
How much more rope does he
need?
And how much more rope do you need when you use a tennis ball instead of the earth?
Same amount, it will
be Pi of the 1 meter.
First off.
You need to know where this person tied the rope around the world because you mention 40,000 km, though I do not believe that that would be enough in certain places, also if he was to use the equater for example this person would need to use ways of supporting his rope around the world, therefore I believe he is bragging or lying.
Then you state fool # 2 where he wishes to use sticks , you would need to know the exact thickness of the sticks cosidering the fact that you would need to wrap the rope/string around the stick each time a stick is used.
Then for the tennis ball as of the same with all above you need to know the accurate size or ammount of air pressure in the ball, or how tighly wraped the sring would be. they are all fools, in the manner of attempting something that cannot be done there also is not enough info stated to provide any answers from one fool to another either... I could go on more in depth but....
Good calculation, MellowGemini....also you need to know the size of the sticks....how tall they are, because you need to add more rope since the earth is not flat but rounded...etc. etc. etc.
That is why I stated I could go more in depth...
I figured that much which you just stated but did not want to cram up the page and write forever, for they are simply fools. and that is the answer of the riddle, the answer is trully that they are fools because they provide no info form one to another. The answer is the oppening statement Craven made.
My mind goes off so fast..
See my mind goes off so fast that all my info that I could add in certain subjects, gets lost and dissapears before I have a chance to type it. My mind at times is like a washing machine on spin cycle that does not cease to stop limiting me to only the random shaking of an uneaven load.
Mellow, this is a simple riddle. The practicality of the absurd endeavor has nothing to do with the answer.
It's just simple math. Let's rephrase it:
A smooth ball with a 40,000 mile equator replaces earth.
the 2nd fool wants to suspend it a meter high.
That's all you need.
New amount = 2 PIx(R+1)
Old amount = 2 PIxR
Difference =2 PI metres
However since 40.000 KM of rope is not itself accurate, and 6 (ish) metres is not a statistically significant difference from this, the logical answer is "the same rope will do". The size of the tennis ball is irrelevent provided it is smaller than the earth.
Ok, I'm gonna let this one die a natural death and just say it's a bad riddle:
6 meters 28 centimeters.
x=2*PI*(r+1)-2*PI*r
x=2*PI*r+2*PI-2*PI*r
x=2*PI
x=6.28
It does not matter what the radius of the circle is. You always need 2*pi more rope.
And who said it was a bad one?????? It wasn't me, honestly... :wink:
I'll take the pi , give the rope to the fool!
I don't know, find some fool to calculate that.
You would have to add twelve feet
what kind of riddle is that. it makes like totally no sense.
Wow Craven, I wish I had seen this riddle before.
I actually knew the answer.
