Hello!</h2>
The answer is:
1017.88 square feet are blue.
<h2>Why?</h2>
To calculate how many square feet are blue, we need to calculate the area of the bottom of the circular swimming pool.
We need to remember that we can calculate the area of any circle using the following formula:

Now, we know that the diameter of the bottom is equal to 36 feet, so, we can calculate the radius of the bottom using the following formula:

So,

Then, calculating the area we have:

Hence, we have that 1017.88 square feet are blue.
Have a nice day!
Answer:
The answer is 15.4
Step-by-step explanation:
hope this helps
1.3 + 12 =13.3+2.1=15.4
7 + 14x means that a number x (x could be any real number) times 14 is added to 7.
So if x = 2:
7 + 14x = 7 + 14(2) = 28 + 7 = 35
