Answer:
1 min 12 seconds
Step-by-step explanation:
Cylindrical pipe-
r=4 cm
rate of flow of water=20m per minute
=2000cm per minute
=2000/60 cm per second
Height of the cylinder=200/6 cm
Volume=pi*r*r*h
=(22/7)*4*4*200/6
=1676.1904
Conical tank-
r=40cm
h=72cm
Volume=(1/3)*pi*r*r*h
=(1/3)*(22/7)*40*40*72
=120685.7142
Time taken=Volume of cone/Volume of cylinder
=120685.7142/1676.1904
=72s
=1 min 12s
