Answer:
Step-by-step explanation:
It is given that 7 litre volume of water is emptied per second.
The total volume of hemispherical sphere
= 1/2 (4πr³/3)
=2πr³/3
=2π(4.2/2)³/3
=2(22/7)(2.1)³/3
=(44/7)×2.1×2.1×2.1/3
=44(0.3)(4.41)/3
=4.4×4.41
=19.4m³
=19400liters
Total time taken with speed of 7 l/s
=19400/7
=2771sec
