Question

A sphere of diameter 18 cm is drawn into a cylindrical vessel of diameter 36 cm atlee filled with water

Answer 1

Answer :-

Step by step explanation:

Volume of sphere :-

$= \frac{4}{3} \pi {r}^{3}$

r = 1/2d = 9cm

$= \frac{4}{3} \times \frac{22}{7} \times 9 \times 9 \times 9 \\ \\ = 3053 {cm}^{3}$

$1 {cm}^{3} = 1ml \\ 3053 {cm}^{3} = 3053ml = 3.053l$

Answer 2

sphere

d=18

r=9

volume of sphere =(4/3)π r^3

=(4/3)π (9)(9)(9)

=(4)π(3)(9)(9)

cylinder

d=36

r= 18

h = to find

volume =πr^2h

=π (18)(18)h

if we equal we find height of water increase

π(18)(18)h=π(4)(3)(9)(9)

cancel π bothside

h = 3
