Answer 1

Answer:

We know that,

Volume of cylinder =πr

2

h

=π×(6)

2

×5

=180πcm

3

=562.5cm

3

(b) Volume of rise water in cylinder when body submerged = Volume of body

πr

2

H=

3

4

π(2)

3

6

2

H=

3

4

×8

H=

108

32

cm

Hence,

rise in water level is H=

108

32

cm

Answer 2

the volume of the stone is 2 cm cube as u have to minus the the total volume bye the volume when the stone removed which is 20 - 18 which is 2
