Question

Find the volume of the sphere. Round your answer to the nearest tenth.

Answer 1

Step 1: $V=\frac{4}{3}{\mathrm{\pi r}}^3$

Convert diameter to radius

$Radius=\frac{14}{2}=7m$

Step 2:

$$\begin{gathered} =\frac{4}{3}\mathrm{\pi }{\left(7\right)}^3\mathrm{Substitute} \\ =\frac{1372}{3}\mathrm{\pi } \\ =1436.75\mathrm{Use}\mathrm{calculator} \end{gathered}$$

Final Answer: The volume is about $904.77cubicm.$
