Question 626344: A cylinder has its height doubled and its radius cut to one-third. What is the ratio of the volumes of the modified cylinder to the original cylinder?
I have the volume of the modified cylinder to be (pi)(1/9)(r^2)(2h) and the original cylinder to be (pi)(r^2)h.
Solving this my answer would be 18:1.
Is this correct?
Thanks
