Given a sphere with diameter, d, the volume, V, of the spere is given by
[tex]V=\frac{\pi d^3}{6}[/tex]Take
[tex]\pi\approx3.14[/tex][tex]\begin{gathered} \text{therefore,} \\ V=\frac{3.14d^3}{6} \end{gathered}[/tex]A basketball is a sphere.
For the men's basketball,
d = 9.4 and
[tex]V=\frac{3.14(9.4)^3}{6}\approx434.7\text{inches}^3[/tex]For women's basketball,
[tex]V=\frac{3.14(9.07)^3}{6}\approx390.5inches^3[/tex]Therefore,
the difference = 434.7 - 390.5 = 44.2 cubic inches
