Hello there !

Can I have some help with this question? Thank you !

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:

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):

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

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

step-by-step explanation:

a.   since the profit made in 2012 is equal to the profit made in 2014, the profit is           symmetric about the line y = 120,000.

step-by-step explanation:

given that megan owns a clothing boutique.

the profits of 2010, 11, are recorded and shown as follows:

years since     2010 0     1     2     3       4       5

profits made in 1000's   39       84     111     120   111     84

we find that profit gradually increases form 2010 to 2013 upto 120,   then starts decreasing.

the profits for 2012 and 2014 are the same while that of 2011 and 2015 are also the same.

this shows that there is symmetry about the line profit = 120000

hence answer is:

a.   since the profit made in 2012 is equal to the profit made in 2014, the profit is           symmetric about the line y = 120,000.
