Question

How many balls, each of diameter 2 cm can be made from a solid sphere oflead of
radius 10

Answer 1

Answer:

Volume of the spherical ball of radius 8 cm

=34π×83cm3

Also, volume of each smaller spherical ball of radius 1 cm

=34π×13cm3

Let n be the number of smaller balls that can be made. Then, the volume of the larger ball is equal to the sum of all the volumes of n smaller balls.

Hence, 34π×n=34π×83

⇒n=83=512

Hence, the required number of balls =512.
