Use three. 144 pi or the pie button and round to the nearest hundredth volume of cone? 

Given:
radius = r = 4.5 cm
height = 9 cm
Required:
The volume of the cone
Explanation:
The formula for volume of cone is given by
[tex]volume\text{ }of\text{ }cone=\frac{\pi r^2h}{3}[/tex]Substituting the given values in the formula we get
[tex]\begin{gathered} volume\text{ }of\text{ }cone=\frac{\pi\times4.5^2\times9}{3}=\pi\times20.25\times3 \\ volume\text{ }of\text{ }cone=60.75\pi\text{ }cm^3 \\ \\ volume\text{ }of\text{ }cone=60.75\pi=60.75\times3.14 \\ volume\text{ }of\text{ }cone=190.755\text{ }cm^3 \end{gathered}[/tex]Final answer:
The volume of cone is 190.75 cubic cm
