Question

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

Answer 1

Given:

radius = r = 4.5 cm

height = 9 cm

Required:

The volume of the cone

Step-by-step explanation:

The formula for volume of cone is given by

`volume\text{ }of\text{ }cone=(\pi r^2h)/(3)`

Substituting the given values in the formula we get

`\begin{gathered} volume\text{ }of\text{ }cone=(\pi*4.5^2*9)/(3)=\pi*20.25*3 \\ volume\text{ }of\text{ }cone=60.75\pi\text{ }cm^3 \\ \\ volume\text{ }of\text{ }cone=60.75\pi=60.75*3.14 \\ volume\text{ }of\text{ }cone=190.755\text{ }cm^3 \end{gathered}`

Final answer:

The volume of cone is 190.75 cubic cm
