Question

a solid sphere of radius 3 cm is melted and then recast into small spherical balls each of diameter 0.6cm. find the number of small balls obtained​

Answer 1

Answer:

125balls

Step-by-step explanation:

Vol of solid sphere of radius 3cm =4/3pi R^3

Vol of small spherical ball of radius 0.6cm =4/3 pi r^3

No of spherical balls ----N= 4/3pi R^3 /4/3 pi r^3 = 27/0.216 =125

Answer 2

Answer:

Number of balls of radius 0.6cm made = 125
