volume of sphere = 4/3πr^3
that means volume is directly proportional to r^3
V1/V2 =( r1/r2)^3
=(5/9)^3
=125/729

Hey,sup!
Ratio of radii= 5:9.
r1=5 , r2=9.
Ratio of volume=>4/3πr1^3:4/3πr2^3.
4/3π will be cancelled out from both sides.
=r1^3:r2^3.
=5^3:9^3.
= 125:729
Ratio of their volume is 125:729.
Hope it helps.
