In a rain-water h

Answer :

Volume of rain fall = Volume of water in cylindrical tank


For cylindrical tank,


Base diameter = 2 m


Base radius,


Height of tank, h = 3.5 m


And we know, volume of cylinder = πr2h


Where, r is base radius and h is height of cylinder


Therefore,


Volume of water in tank = π(1)2(3.5)



Volume of rain fall = area of roof × height of rain fall


Let the height of rainfall be 'h'


11 = length × bread th × h


11 = 22× 20 × h


1 = 40 h


h = 0.025 m


h = 2.5 cm [As 1 m = 100 cm]


Therefore, height of rain fall is 2.5 cm


Water conservation is very necessary, as water is an essential unit of life and life is not possible without water.
