Question

How many balls of diameter 1 cm can be made from an iron ball of diameter 8 cm.

Answer 1

Answer:

512

Step-by-step explanation:

Let the number of balls made=s n

Volume of the sphere = 4/3 πr3

The volume of the solid sphere = sum of the volumes of n spherical balls.

n x 4/3 πr3 = 4/3 πR3

n x 4/3 π(1)3 = 4/3 π(8)3

n = 8^3 = 512

Hope this helps :)
