Help me with this mofo riddle!

[Insanatos]

K, my professor decided to have some fun with us and gave us a riddle to do for extra credit. Here it is:

"Gandalf took a piece of paper 5" by 12" and made a cylindrical can with it. He then put a top and bottom on the can and computed the can's surface area. Frodo did the same with another 5" by 12" piece of paper, getting a larger surface area. How much larger was Frodo's surface area than Gandalf's?"

I've been trying to figure it out for about 15 minutes and gave up. Any help?

[Forgettable]

They rolled the paper in the other direction, thus granting larger top and bottom with more surface area.

Think of a tall skinny pop can...
Then think of a short fat pop can.

Edit: Oh I didn't read the "How much larger" part. Uhm. I'm about to get off the computer so I will leave you to figure out the "How much larger" part.

Thanks.

10char.

Gandalf's a wizard. I mean...that answer seems pretty obvious.

Ya I can do it now, thanks.

2r*pi=circumference is the equation.

Gandalf's circumference=5 so you put that in.

2r*pi=5

Juggle it about a bit and you get

5/pi=2r

Play with that and you'll get the radius. pi*r^2 is the area of a circle. Pop in the r (which you just calculated). Double it (two ends of the can) and add to 5*12.

Repeat for Frodo's 12" can and work out the difference. It's an exercise in breaking down a puzzle.

Jokingly: the answer should be who the hell cares, why arent they in mordor yet??!?!

Trying: well i suppose what conzar is saying would be more accurate then what i could come up with in about 8 minutes of thinking, so go with that =]

Got the answer.. Frodo's is 7.04" larger surface area than Gandalf's. I used 3.14 instead of Pi, so if any of you do it, your answer may be a little off.

No, NO, NO!



Use a smartass answer.



"Gandalf is a Wizard."

This is so worth getting a failing note for. ^.^

One does not simply ask politely for help with a maths problem into Mordor!!!

[Verdris]

How did Frodo find time to roll a piece of paper in his busy schedule of staring at the ring and gazing longingly at Sam?

I actually did that once way back when I was in high school. We had a bunch of sentences where we had to fill in the blanks and I made a story with the words I put in the blanks (that had absolutely nothing to do with the assignment). Teacher gave me an A for wittiness and creativity.
