<span>Step 1: find the radius
The radius is half of the diameter. So the radius is 8 because the diameter is 16.
Step 2: square the radius.
8^2 = 64
Step 3: plug into formula
pi * radius squared * height
3.14 * (64) * (1.8) = 361.728 m^3
The volume of the pool is 361. 728 meters cubed.
Step 4: Divide volume by the amount pumped out per hour
volume / amount pumped out = amount of hours
361.728/16 = 22.608 hours.
So your answer is approximately 23 hours.</span><span>

Answer:

- <em>It takes</em><u> 2.5 minutes </u><em>to fill the tank.</em>
Explanation:
The net speed or net rate for filling the 10-liters tank is equal to the speed the tap is filling less the speed the water is leaking through the hole located at the bottom of the tank:
- Net rate = rate of filling - rate of leaking
- Net rate = 5 liters/minute - 1 liter/minute
- Net rate = 4 liters/minute
Thus, consiedering the tank is empty at the beginning, the time is:
- Time = Volume of the tank / net rate of filling
- Time = 10 liters / (4liters/minute)
- Time = 2.5 minutes ← answer
We are given the inequality,
Now let us simplify this to get the value of a,
Adding 15 to both the sides,
So we have a>10 and a<17
One more thing that we need to look at is whether we will have close dots or open dots at 10 or 17.
If we have "=" sign along with inequality sign (≤ or ≥) then we use closed dot.
If we dont have "=" sign along with inequality sign (< or >) then we use open dot.
In our case we use open dot , since we dont have "=" sign.
So Answer will be option third, line starting from 10 to 17 with open dots at 10 and 17.
