Answer:
104°
Step-by-step explanation:
The principle to apply here is that angle subtended at the center of a circle is twice the angle at circumference.
Angle subtended at arc = 52°
Angle at the center = 2 x 52° = 104°

Answer:
Therefore the tank will be half empty after 10.10 days.
Therefore there will be 2735.53 liters water in the tank after 4 days.
Step-by-step explanation:
Given that,the square root of the volume of remaining water in the tank is proportional to the rate of water leakage.
Let V be volume of water at any instant time t.
where k is constant of proportionality.
Integrating both sides
[ C is integrating constant]
At t=0, the volume of water is 350 liters
The equation becomes
Again at t=1, the volume of water is(350-20)liters=330 liters
The equation becomes
Now when the tank is half empty,then V= (350÷2) liters = 175 liters
days
Therefore the tank will be half empty after 10.10 days.
After 4 days,
liters
Therefore there will be 2735.53 liters water in the tank after 4 days.
