Answer:
Option d. 3.14 minutes.
Explanation:
To answer this question, we first determine the volume of the inverted cone through the equation,
V = Bh/3
where B is the area of the base and h is the height.
V = (π)(3 in)²(4 in) / 3
V = 37.68 in³
Now the liquid drips at the rate of 12 in³ every minute, divide the rate of the water dripping by the number of house,
n = (37.68 in³)/12 in³/min
n = 3.14 mins
It would take 3.14 minutes for all the liquid to pass through the nozzle.
