Answer 2

Answer:

1728

Step-by-step explanation:

Radius of ball = 1 cm

So, volume of ball = $\frac{4}{3} \pi r^3$

                                      = $\frac{4}{3} \pi (1)^3$

                                      = $4.18879020479$

radius of lead sphere = 12 cm

So, volume of Sphere = $\frac{4}{3} \pi r^3$

                                      = $\frac{4}{3} \pi (12)^3$

                                      = $7238.22947387$

Thus the number of balls can be made :

=$\frac{\text{Volume of sphere}}{\text{Volume of ball}}$

=$\frac{7238.22947387}{4.18879020479}$

=$1728$

Hence 1728 balls can be made .
