Question

If you roll a 8.5" x 11" paper into a cylinder, what is the radius?

Answer 1

Hoot! You just asked your first question! Hang tight while I find people to answer it for you. You can thank people who give you good answers by clicking the 'Good Answer' button on the right!

Answer 2

first answer: 4.25/(Pi) if rolling it with the 8.5 side down
second answer: 5.5/(Pi) if rolling with the 11 inch side down

Answer 3

how did you get that?

Answer 4

I agree completely with Rubin!

Answer 5

Can you explain to me how you got that? I have to show my work.

Answer 6

sure. the equation for circumference is 2(Pi)R. so since you know the final Circumference (8.5, or 11) you should lay it out like this: 2(Pi)R=(8.5 or 11). then you divide each side by 2, and divide each side by Pi to get (4.25/Pi or 5.5/Pi).. hope that helps

Answer 7

Ok, that is what I thought. But then I got confused with my answer lol. So when I roll the 8.5" sides making the cylinder's height 8.5", it's radius is 5.5"? And vise versa?
