Question

Please tell me answer of this question in easy way but Step-by-step
a metallic sphere of radius 3 cm is melted and then cast into small spherical balls of diameter 0.6 M find the number of balls obtained?

Answer 1

Hey dude!!

Hope it is correct!!!!!!..

Answer 2

Hello friend

Radius of bigger sphere (R) = 3cm

Radius of smaller balls (m)= 0.6/2= 0.3 cm.

Let the number of small balls = x

x × Volume of small balls = Volume of bigger sphere

$x \times \frac{4}{3} \pi {r}^{2} = \frac{4}{3} \pi {m}^{2} \\ \\ x = {} \frac{ {m}^{2} }{ {r }^{2} } \\ x = \frac{3}{0.3 } \\ x = 1000$
