Question

how many lead balls each of radius 1 cm can be made from a sphere of radius 8 cm

Answer 1

Answer:

Step-by-step explanation:

lead balls are in shape of sphere so volume of 1 sphere =4/3 x pi x 1^3

=4/3 pi

now volume of big sphere =4/3 x pi x 8^3

=512 x pi x 4/3

=dividing the volume of larger sphere by smaller one

=we get 512 spheres
