Question

Find the volume of a cone. Round your answer to the nearest tenth.

Answer 1

Step 1: Calculate the radius of cone

$\mathrm{Radius}\mathrm{r}=\frac{\mathrm{Diameter}}{2}=\frac{9}{2}=4.5\mathrm{m}$

Step 2: Calculate the volume of cone

We know that , Volume of cone $V=\frac{1}{3}{\mathrm{\pi r}}^2\mathrm{h}$

$$\begin{gathered} =\frac{1}{3}\mathrm{\pi }{\times (4.5)}^2\times \left(4\right) \\ =84.82 \end{gathered}$$

Hence, The volume is about 84.82 cubic m.
