I hope it will help you

Answer 2

$\frac{4}{3} \pi *8^{3}$Answer:

512 balls

Step-by-step explanation:

Here, we are melting the ball of radius 8 cm and are making other balls with it.

Let the number of balls be n.

Then, we have:  

Volume of the lead sphere(R= 8cm) = sum of the volumes of the balls(r= 1cm)

we know that, volume of a sphere =  $\frac{4}{3} \pi r^{3}$

now, we have,   $\frac{4}{3} \pi R^{3}$= $n* \frac{4}{3} \pi r^{3}$

after substituting the values, we get:

$\frac{4}{3} \pi*8^{3}$ =$n*\frac{4}{3} \pi*1^{3}$

=> n=512.

So, we will get 512 balls out of a sphere of radius 8 cm.
