Question

PLEASE HELP!!!!

The dimensions of a conical funnel are shown below:



Lolita closes the nozzle of the funnel and fills it completely with a liquid. She then opens the nozzle. If the liquid drips at the rate of 12 cubic inches per minute, how long will it take for all the liquid to pass through the nozzle? (Use π = 3.14.)

Answer 1

Answer: D) 3.14 minutes

Answer 2

To answer this item, we first determine the volume of the inverted cone thru 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
Then, divide the rate of the water dripping by the number of house,
n = (37.68 in³)/12 in³/min
n = 3.14 mins
