Question 200090
Suppose the height and the radius of the original cylinder are h and r respectively. Then the volume of the original cylinder is 
{{{v = pi*r^2*h}}}

The height and the radius of the newly formed cylinder are 3h and r/3 respectively. Then the volume of the newly formed cylinder is 
{{{V = pi*(r/3)^2*3h}}}
={{{pi*(r^2/9)*3h}}}
={{{(1/3)*pi*r^2*h}}}
={{{(1/3)*v}}}
So the volume of the newly formed cylinder is only one third of the volume of the original cylinder.
