Answer:
[tex]\large\boxed{V=\dfrac{32}{3}\pi\ cm^3}[/tex]
Step-by-step explanation:
[tex]\text{The formula of a volume of a sphere:}\\\\V=\dfrac{4}{3}\pi R^3\\\\R-radius\\\\\text{A diameter}\ D=2R\Rightarrow R=\dfrac{D}{2}.\\\\\text{We have}\ D=4\ cm\to R=\dfrac{4}{2}\ cm=2\ cm\\\\\text{Substitute:}\\\\V=\dfrac{4}{3}\pi(2)^3=\dfrac{4}{3}\pi(8)=\dfrac{32}{3}\pi\ cm^3[/tex]
