The value could be rewritten as 2(x+4)
44 = 4x + 12
32 = 4x
X = 8 months after February = October of the same year. That's choice (b).
Answer:
20/(9π) m/min ≈ 0.707 m/min
Step-by-step explanation:
The rate of change of height is the rate of change of volume divided by the surface area. Of course, the surface area is given by πr², where r = d/2 = 3 m.
dh/dt = (dV/dt)/A = (20 m³/min)/(π(3 m²))
dh/dt = 20/(9π) m/min ≈ 0.707 m/min
