Nisha 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 15 cubic inches per minute, how long will it take for all the liquid to pass through the nozzle? (Use π = 3.14.) (1 points)

3.14 minutes
5.02 minutes
2.51 minutes
3.76 minutes

its the second one @grex10

elonasushchik · Answer

First you need to find the volume of the cone

elonasushchik · Answer

The volume of any cone with radius 'r' and height h is

V = (pi*r^2*h)/3

elonasushchik · Answer

which is 75.36

elonasushchik · Answer

Once you know the volume of the cone, you can use it to figure out how long that amount of liquid will take to drip out of the cone

elonasushchik · Answer

Now we have this idea

Amount dripped out = (Rate of drip)*(Time)

elonasushchik · Answer

So this means

Amount dripped out = (Rate of drip)*(Time)

75.36 = 15*t

where t is the time

Note: we set "Amount dripped out" to all 75.36 cubic inches because want all the liquid to drip out

elonasushchik · Answer

So your last step is to solve for t which is 5.024
