The globe is a sphere.
The volume of a sphere is given as
[tex]\frac{4}{3}\pi r^3[/tex]
The diameter =30 inches
the radius =30/2=15 inches
[tex]\begin{gathered} \text{The volume of the globe=}\frac{4}{3}\times3.14\times15^3 \\ =\frac{4}{3}\times3.14\times3375 \\ =4\times3.14\times1125 \\ =14130. \end{gathered}[/tex]
Hence the volume of the globe is
[tex]14130\text{cubic inches}[/tex]
Therefore the volume of the globe is 14130 cubic inches
