Volume of sphere when radius is 7 cm = 4/3πr³ = 4/3π x 343 cm³
Volume of sphere when radius is 14 cm = 4/3π x 2744 cm³
Ratio = 343/2744 = 1/8 = 1: 8
Hope This Helps You!

Volume of Spheres =(4/3)πr³
Volume of sphere is directly proportional to r³ .k stands for (4/3)π
So V1 = k (7)³= 343k c.m³
V2 = k(14)³=2744k c.m³
V1/V2= 343/2744=1/8
V1:V2= 1/8
Hope u understand
