Question

diameter of a sphere is 0.7 CM if 3000 spheres, completely filled the water, are drawn out from a water tank then find volume of water drawn out​

Answer 1

The volume of water drawn out would be 539 cm³

Given, the diameter of 1 sphere = 0.7 cm = 7/10 cm

We know, radius = diameter/2

= 7/(2*10) cm = 7/20 cm

For a sphere of radius r cm, its volume will be (4/3)Пr³

Thus for the sphere of radius 7/20 cm, its volume will be equal to

(4/3)*(22/7)*(7/20)³                               [П = 22/7]

=  539/3000 cm³

Similarly, for 3000 such spheres, their volume would be equal to,

3000*(539/3000) cm³

= 539 cm³

This is the required answer.
