SOLUTION
Consider the image below,
The lenght of the compass is the radius, using a lenght of 5 unit, we have circle below as the sphere .
Where
[tex]\begin{gathered} r=\text{ radius, O= origin } \\ And \\ r=5\text{unit } \end{gathered}[/tex]
Using the formula, we have
[tex]\begin{gathered} \text{Volume of sphere} \\ =\frac{4}{3}\pi r^3 \\ \text{where} \\ \pi=3.14,\text{ r=}5 \end{gathered}[/tex]
Substitute into the formula, we have
[tex]\begin{gathered} \text{Volume of the sphere is } \\ =\frac{4}{3}\times3.14\times5^3 \\ \text{Hence } \\ 523.33\text{ cubic unit} \end{gathered}[/tex]
Therefore
The volume of the sphere is 523.33 cubic unit
