Answer:
Water level in the reservoir is falling at the rate of 0.398 ft per minute.
Step-by-step explanation:
From the figure attached,
Water level in the reservoir has been given as 10 feet and radius of the reservoir is 4 feet.
Let the level of water in the reservoir after time t is h where radius of the water level becomes r.
ΔABE and ΔCDE are similar.
Therefore, their corresponding sides will be in the same ratio.
--------(1)
Now volume of the water V =
From equation (1),
V =
V =
Since feet³ per minute and h = 5 feet
feet per minute
Therefore, water level in the reservoir is falling at the rate of 0.398 feet per minute.
