Question

The rainwater deposited on o 30 m x 25 m roof is collected in a cylindrical tank of dimeter is 8 m
and height 12 m. If the tank is completely filled, find the height of the water collected on the roof.

Answer 1

radius = 4 m
height = 12 m
volume of cylinder =
22/7 *4*4*12
22/7 *192
22*27.42
603.24


lenght = 30 m
breadth = 25 m
volume of cuboid =l*b*h
30*25*h=603.24
750*h =603.25
further division will give you the height
