Question

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

Answer 1

Step 1:

Volume of sphere $=\frac{4}{3}{\mathrm{\pi r}}^3$

Convert diameter to radius

$\mathrm{Radius}=\frac{12}{2}=6\mathrm{mm}$

Step 2:

$$\begin{gathered} =\frac{4}{3}\mathrm{\pi }{\left(6\right)}^3\mathrm{Substitute} \\ =\frac{364.5}{3}\mathrm{\pi } \end{gathered}$$

Step 3:$=904.77$ Use calculator

Final Answer:: The volume is about 904.77 cubic mm.
