Answer:

The answer is the option B

The volume of the cylinder increases by a factor of $18$

Step-by-step explanation:

we know that

The volume of a cylinder is equal to

$V1=\pi r^{2}h$ ------> original volume

In this problem

$h=2h\ units$

$r=3r\ units$

substitute in the formula

$V2=\pi (3r)^{2}(2h)$

$V2=18\pi r^{2}h$

$V2=18V1$

therefore

The volume of the cylinder increases by a factor of $18$
