Hello from MrBillDoesMath!

Answer:  The cylinder on the left has 4 times the volume of the cylinder on the right.

Discussion.

The volume of a cylinder of height "h" and radius "r" is given by

PI * r^2 * h                     (r^2 signifies r squared)

(Think of this formula as the area of the circle or radius r multiplied by the height the circle is pushed "up" to create the cylinder)

The volume of the cylinder on the left is:    Pi * 4^2 * h =   16 Pi *h

The volume of the cylinder on the right is: Pi * 2^2 * h =   4 Pi *h


As 16/4 = 4, the cylinder on the left has 4 times the volume of the one on the right.


Thank you,  

MrB
