Answer 1

Answer:

About 6 hours.

Step-by-step explanation:

The cylinder has a diameter of 10 meters and a depth of 1.4 meters.

First, we can find the volume of the cylinder, given by the formula:

$V=\pi r^2h$

Where r is the radius and h is the height (or depth, in this case).

Since our diameter is 10, our radius is 5.

Therefore, the volume of the cylinder will be (using 3.14 as π):

$V=(3.14)(5)^2(1.4)=109.9\text{ meters} ^3$

Since water is pumped at a rate of 18 cubic meters per hour, it will take then:

$109.9/18=6.10\overline{5}\approx 6\text{ hours}$

So, it will take about 6 hours for the water to completely fill the pool.
