The volume of a sphere is:
Since we know V = 996 cm^3, then we need to find r
[tex]\begin{gathered} V=\frac{4}{3}\pi r^3 \\ r^3=\frac{3}{4}\cdot\frac{V}{\pi} \\ r=\sqrt[3]{\frac{3}{4}\cdot\frac{V}{\pi}} \\ r=\sqrt[3]{\frac{3}{4}\cdot\frac{996}{\pi}} \end{gathered}[/tex]
The value of r is 6.195, but approaching to the nearst tenth, r = 6.2
