Answer:
45781.2\text{ cm}^3

Explanation:

From the given picture, the diameter of the base of cylinder = 12 cm

i.e. the radius of the cylinder =
r=(12)/(2)=6\ cm

Height = 15 cm

If the dimensions of the following cylinder are tripled, then the radius of cylinder =
3*6=18\ cm

Height=
3*15=45\ cm

We know that the volume of a cylinder is given by :-


\text{Volume}=\pi r^2 h\\\\\Rightarrow\\text{Volume}=(3.14)(18)^2(45)\\\\\Rightarrow\text{Volume}=45781.2\text{ cm}^3
