Answer 2

Answer:

the number of balls = 729

Step-by-step explanation:

Given = radius of smaller balls,r = 1 cm

diameter of bigger balls = 18cm

radius of bigger balls,R = 9cm

volume of smaller balls = 4/3πr^3

= 4/3π(1)^3

= 4/3π

volume of bigger balls = 4/3πR^3

=4/3π 9*9*9

let the number of balls be "n"

n = volume of smaller balls/volume of bigger balls

n = 4/3π/4/3π* 9*9*9

n = 4/3π/4/3π * 729

n = 729
