The volume of soccer ball is

\(V_(soc cer)=4/3pir^3\)

diameter of ball s 1.1 times therefore the volume of the basketball is

\(V_(basketball)=4/3*pi*(1.1r)^3\)

\(V_(basketball)=4/3*pi*1.331*r^3\)

\(V_(basketball)=1.331V_(soc cer)\)

since the diameter of tennis ball is about 0.3 times that of a scoccer ball it's radius is also 0.3 times

\(V_(ten nis)=4/3*pi*(0.3r)^3\)

\(V_(ten nis)=4/3*pi*0.027*r^3\)

\(V_(ten nis)=0.027_(soc cer)\)
