Question

The rain falls 10cm on a particular day. The rain water that fals on a roof 70m long and 44m wide was collected in a cylindrical tank of radius 14m, find:- (a) Volume of the that falls on the roof. (b)Rise of water level in the tank due to rain water

Answer 1

volume of water in the roof= 70×44×0.1
                                       =308m³
volume of cylindrical tank=(14)³
                                     =2744m³
volume in cylindrical tank=2744-308
                                    =2128m³
rise in water level=∛2128
