Answer: We have to find the volume of a sphere, provided its radius:
[tex]R_{sphere}=13\operatorname{cm}[/tex]The formula for sphere volume is:
[tex]V_{sphere}=\frac{4}{3}\pi R^3[/tex]Therefore now we can find the volume, because we have the value of the Radius of the sphere, and we do it next.!
[tex]\begin{gathered} R_{sphere}=13\operatorname{cm} \\ \rightarrow\therefore\rightarrow \\ V_{sphere}=\frac{4}{3}\pi(13\operatorname{cm})^3=\frac{4}{3}\pi2197\text{ cm}^3 \end{gathered}[/tex]Simplification gives:
[tex]V_{sphere}=9198.107\text{ cm}^3[/tex]
