Radius of pipe = 2 cm
Rate of water flow = 20 m/min = 2000 cm/min
Volume of water flowing in pipe in 1 min. = π * 2 * 2 * 2000 cm3
Radius of base of conical tank = 40 cm
Depth of tank = 72 cm
Volume of tank = 1/3(π * 40 * 40 * 72) cm3
Time taken to fill the tank = (π * 40 * 40 * 72)/(π * 2 * 2 * 2000 * 3)
= 24/5 =4.8 minutes = 4 min + .8*60 secs
= 4 minutes and 48 seconds ANS.
