Question

How many spherical balls of radius 1 cm can be made by melting a big ball whose diameter is 8 cm? ​

Answer 1

Answer:

64

Step-by-step explanation:

volume of the big ball = volume of the spherical ball × n

radius of big ball ( r1) = 4cm

radius of spherical ball (r2)= 1cm

4/3πr1^3=4/3π r2^3 × n

4^3 = 1^3×n

64 = n
