sleet_krkn [62]

Answer: We have to find the volume of a sphere, provided its radius:

$R_{sphere}=13\operatorname{cm}$

The formula for sphere volume is:

$V_{sphere}=\frac{4}{3}\pi R^3$

Therefore now we can find the volume, because we have the value of the Radius of the sphere, and we do it next.!

$\begin{gathered} R_{sphere}=13\operatorname{cm} \\ \rightarrow\therefore\rightarrow \\ V_{sphere}=\frac{4}{3}\pi(13\operatorname{cm})^3=\frac{4}{3}\pi2197\text{ cm}^3 \end{gathered}$

Simplification gives:

$V_{sphere}=9198.107\text{ cm}^3$
