Answer 2

Answer: $45781.2\text{ cm}^3$

Step-by-step explanation:

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

i.e. the radius of the cylinder =$r=\dfrac{12}{2}=6\ cm$

Height = 15 cm

If the dimensions of the following cylinder are tripled, then the radius of cylinder =$3\times6=18\ cm$

Height=$3\times15=45\ cm$

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

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