2144.7 m³
1) Since that sphere has a radius of 8m then we can plug it into the Volume formula of the sphere, as it follows:
[tex]\begin{gathered} V=\frac{4}{3}\pi\cdot r^3 \\ V=\frac{4}{3}\pi\cdot8^3 \\ V=2144.66\approx2144.7m^3 \end{gathered}[/tex]2) So the volume of that Sphere is approximately 2144.7 m³
