The volume of a sphere is
[tex]V=\frac{4}{3}\pi(r)^3[/tex]Since the tennis ball is shaped like a sphere, then we will use the rule above to find its volume
Since its radius is 40 mm, then
r = 40 mm
[tex]\begin{gathered} V=\frac{4}{3}\pi(40)^3 \\ V=268082.5731 \end{gathered}[/tex]The volume of the table tennis ball is about 268082.57 mm^3
