Question

14. How many spheres of equal radii may be formed by melting a big sphere such that the radius
of a smaller sphere is 1/8 of the radius of the original sphere?​

Answer 1

Answer: the answer is

Take a sphere, radius is 'r'

New radius 'R'

According to the question, 1/8×R=r or r×8=R

Step-by-step explanation:

Volume of the first small sphere= 4/3πr^3

Volume of new sphere is 4/3πr^3×8 (r×8=R)

Therefore the number of spheres needed are

4/3πr^3×8 / 4/3πr^3= 8
