Question

Find the amount of water displaced by a solid spherical ball of diameter 4.2 cm,when it is completely immersed in water

Answer 1

Diameter= 4.2 cm
Radius=4.2/2cm=2.1cm
Volume of spherical ball=4/3πr^3(r=radius)
=4/3*22/7*2.1*2.1*2.1/10*10*10 sq.cm
=38808 sq.cm
Now 1 litre= sq. decameter
or 38808sq.cm = 38.808 decameter =38.808 litre
Therefore when the spherical ball is completely immersed in water then the amount of water displaced is 38.808litre

Answer 2

Answer:

Diameter= 4.2 cm

Radius=4.2/2cm=2.1cm

Volume of spherical ball=4/3πr^3(r=radius)

=4/3*22/7*2.1*2.1*2.1/10*10*10 sq.cm

=38808 sq.cm

Now 1 litre= sq. decameter

or 38808sq.cm = 38.808 decameter =38.808 litre

Therefore when the spherical ball is completely immersed in water then the amount of water displaced is 38.808litre
