Given :
A cylindrical tank with radius 3m is being filled with water at a rate 4m³/min.
To Find :
How fast is the height of the water increasing.
Solution :
We know, volume of cylinder is given by :
....1)
Also, we have given that, .

9. slope: 1/2 y-int: -4
10. y=20x+50
11. y=-40x+300
12. i dnt know
13.9/6+3/6x=y or 1.5+0.5=y
Step-by-step explanation:
10. starts at 50, goes up by 20 per week
11. starts at 300, goes down 40 per week
13.
9+3x=6y
9/6+3/6x=y or 1.5+0.5=y
