The volume of a cylinder is 96 inches cubed. The height of a cylinder is 3 times the height of the first cylinder and the radius of its base is 1/4 times the radius of the first cylinder. What is the volume of the second cylinder?
96=pi*3h*(1/4)(1/2)base, since the height is 3 times taller, and base/2=radius, so (1/2) of a base that is (1/4) as large.
Do that to both sides, and you get:
Or, the new volume is 36 inches cubed.
I misread the question. It should be:
96=pi*3h*1/4r^2. They didn't restate the base. The correct answer is:
72 inches cubed.
