Correct Answer - Option 3 : 64

Given:

The radius of the small sphere, r = 14 cm

The radius of the larger sphere, R = 56 cm

Formula:

The volume of the sphere = (4/3)πr3

Where,

r = radius of the sphere

Calculation:

Let the number of the small spheres be n.

According to the question, we have

(4/3) × π × 14 × 14 × 14 × n = (4/3) × π × 56 × 56 × 56

⇒ n = (56 × 56 × 56)/(14 × 14 × 14)

⇒ n = 4 × 4 × 4

⇒ n = 64

∴ The numbers of small spheres is 64.
