Question

A cylindrical container of base radius 6 cm,has water up to a height of 5cm .find: (a) volume of water. (b) a metal sphere of radius 2 cm is totally submerged in water.find rise in water

Answer 1

a) volume of cylinder=πr^2h
=π(6)^2(5)=180π cm^3
=562.5 cm^3

b) volume of rise water in cylinder when body submergerd =volume of body

πr^2H=4/3π(2)^3
(6)^2H=4/3 x 8
H=32 /108 cm
hence rise water is 32/108 cm

Answer 2

Answer:

a) volume of cylinder=πr^2h

=π(6)^2(5)=180π cm^3

=562.5 cm^3

b) volume of rise water in cylinder when body submergerd =volume of body

πr^2H=4/3π(2)^3

(6)^2H=4/3 x 8

H=32 /108 cm

hence rise water is 32/108 cm
