Step-by-step explanation:
volume of hemispherical tank = 2/3πr³
V = 2/3 × 22/7 × 3 ³
V = 2/3 × 22/7 × 27
V = 396/7 m³
Volume emptied per second = 15/2 litres
to find time taken to half empty the tank
half volume of the tank = 396/7 × 1/2 => 198/7 m³
=> 198/7 × 1000 litres [ 1 m³ = 1000 litres]
time t = 198000/7 ÷ 15/2
t = 198000/7 × 2/15
t = 3771.4 seconds => 1.05 hours
