Question

How many lead balls, each of radius 1 cm, can be made from a sphere of
radius 8 cm ?​

Answer 1

Answer:

I might be wrong but I think 8 lead balls can be made.

Explanation:

Radius = 1 cm

Diameter = (2 × 1) cm

= 2 cm

Radius of the sphere = 8 cm

Diameter of the sphere = (2 × 8) cm

= 16 cm

Therefore,

No. of lead balls = (16 ÷ 2) balls

= 8 balls (Answer)

Answer 2

Que.How many lead balls, each of radius 1 cm, can be made from a sphere of

radius 8 cm ?

ans. in the given sphere

radius=8cm

so volume of sphere=4/3πr³cm³

and it is 2048/3

volume of ball=4/3πcm³

no of balls= volume of sphere/volume of ball

=512 balls
