Question

a spherical ball of radius is melted to make 8 new identical balls each of radius r2 units​

Answer 1

Step-by-step explanation:

let the radius of spherical ball = r

so it's volume =4/3π×r×r×r

radius of ball formed -r2

so it's volume is 4/3π×r×r×r×8

so the both volume are equal

so both volume are equal

so 4/3π cancelled

and r= 8r2
