Homework Statement
Jack and Jill each roll a sheet of 9X12 paper to form a cylinder.
Jack tapes the two 9-inch edges together.
Jill tapes the two 12-inch edges together.
Which is greater?
The volume of Jack's Cylinder
or
The volume of Jill's cylinder.
Homework Equations
Cylinder Volume: V=pi*r^2*h
The Attempt at a Solution
The problem that I was facing with this question was finding the radii.
However, I looked at the solutions and it says that
Jack's cylinder has a circumference of 12
and Jill's cylinder has a circumference of 9
Jack's height is 9
Jill's height is 12
I don't understand how they derived the circumferences ?!
once I know the circumference I can find the radius.
Thanks.
