<PRE><B>Question 331947</B>
The diameter of Cylinder I is 5 and its height is 9.
The diameter of Cylinder II is 10 and its height is 9.
What is the ratio of the volume of Cylinder I to Cylinder II?
..
Volume of cylinder I = pi*(2.5)^2*9
Volume of cylinder II = pi*(5)^2*9

Ratio = pi*(2.5)^2*9/ pi*(5)^2*9
Ratio = 6.25/25
Ratio =1/4</PRE>
