Answer:
[tex]\large\boxed{V=113\ cm^3}[/tex]
Step-by-step explanation:
The formula of a volume of a sphere:
[tex]V=\dfrac{4}{3}\pi R^3[/tex]
R - radius
We have R = 3cm. Substitute:
[tex]V=\dfrac{4}{3}\pi(3^3)=\dfrac{4}{3\!\!\!\!\diagup_1}\pi(27\!\!\!\!\!\diagup^9)=(4\pi)(9)=36\pi\ cm^3\\\\\pi\approx3.14\\\\V\approx(36)(3.14)=113.04\ cm^3\approx113\ cm^3[/tex]
