Question

How many spherical Marbles have a radius r÷2 can be made by melting a solid sphere having radius r

Answer 1

I don't know this question's answer

Answer 2

Radius of spherical marble is r/2
And r of the bigger solid is 4
So,
Volume of spherical marble = 4/3* pie* r^3\2= pie* r^3 /6.............eq 1
Volume of sphere solid= 4/3*r^3...........eq 2


Eq 2/eq1
We get 8
Answer is 8 spheres
Thanks
