Question

Use 3.14 for pi or the pi button and round to the nearest hundredth. The volume of the cone?

Answer 1

Given:-

`r=4.5,h=9`

To find the volume of cone.

So the volume formula for cone is,

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

Substituting we get,

`\begin{gathered} v=3.14(4.5)(4.5)((9)/(3)) \\ v=3.14(4.5)(4.5)(3) \\ v=190.755 \end{gathered}`

So the required solution is 190.76
