Volume of tank=π*1.5*1.5*1.5*(2/3)m^3
Volume of water flowing in 1 sec=(25/7)/1000m^3
Time=33minutes

Answer:
989 seconds
Step-by-step explanation:
Radius =1.5m
Volume of the tank = (2/3)πr³
=(2/3)(3.14)(1.5)³
=7.065m³
=7065 L
Time taken to half the tank at the rate of 25/7 L/s
=(1/2)(7065)(25/7)
=989 seconds
