Question

The rain water from a roof 22 m 20 m drains into a cylindrical vessel having a diameter of 2 m and height 3.5 m. If the vessel is just full, then the rainfall in cm is

Answer 1

Answer:

Step-by-step explanation:

volume of roof= l x b x h

= 22X20 X h

height of roof= height of rainfall

volume of cylinder= 22/ 7 x 1x1 x35/10

and

volume of water on roof = volume of

Water in cylindrical tank

22 X 20 X h = 22/7 1 x 1x35/10

22 X 20 X h = 11

h = 11/440

h = 1/40 m

h = 0.025 m

= 2.5 cm

so the rainfall = 2.5 cm

Answer 2

Answer:

volume of roof = volume of Cylindrical tank

l × b × h = π r² h

22×20×h = 22/7 (1)² × 3.5

On solving the value of h comes out to be,

h = 1/40 m

or h = 2.5 cm

so the rainfall in cm is 2.5 cm.
