Answer: Level of the liquid dropping at 28.28 inch/second when the liquid is 2 inches deep.
Step-by-step explanation:
Since we have given that
Height = 9 inches
Diameter = 6 inches
Radius = 3 inches
So, 
Volume of cone is given by

By differentiating with respect to time t, we get that

Now, the liquid drips out the bottom of the filter at the constant rate of 4 cubic inches per second, ie 
and h = 2 inches deep.

Hence, level of the liquid dropping at 28.28 inch/second when the liquid is 2 inches deep.
Answer:
radius=2
Step-by-step explanation:
if the circumference=4pi and the formula is 2pir then r must be 2 and would look like this:
C = 2pir
C = 2pi2
C = 2*2pi
C = 4pi
.08 x .04 is the right answer
