[tex]r_{1}[/tex] = 6 cm
[tex]r_{2}[/tex] = 9 cm

[tex]v_{1}[/tex] =  [tex]\frac{4}{3}[/tex] x [tex]\pi[/tex] x [tex]r_{1}^{3}[/tex] = [tex]\frac{4}{3}[/tex] x [tex]\pi[/tex] x [tex]6^{3}[/tex] = [tex]\frac{864\pi}{3}[/tex]

[tex]v_{2}[/tex] =  [tex]\frac{4}{3}[/tex] x [tex]\pi[/tex] x [tex]r_{2}^{3}[/tex] = [tex]\frac{4}{3}[/tex] x [tex]\pi[/tex] x [tex]9^{3}[/tex] = [tex]\frac{2916\pi}{3}[/tex]

[tex]v_{1}[/tex] : [tex]v_{2}[/tex] = [tex]\frac{864\pi}{3}[/tex] : [tex]\frac{2916\pi}{3}[/tex] = 864 : 2916 = 8 : 27
