Question

I need help with pie

Answer 1

The volume of Cone is given by

`V=(1)/(3)\pi r^2h`

where the constant Pi is

`\pi=3.14`

and, in our case, the radius r=2 and the height h=9.

By substituting these values into the volume formula, we have

`V=(1)/(3)\pi(2^2)(9)`

which gives

`\begin{gathered} V=(1)/(3)\pi\cdot4\cdot9 \\ V=\pi\cdot4\cdot3 \end{gathered}`

Therefore, the answer is

`V=12\pi`
