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: 3/8, 0.375, 37.5%
Step-by-step explanation:
Count the number of cards with odd numbers that are greater than 4. 5, 7, and 9 are odd numbers greater than 4. There are 3 cards with odd numbers greater than 4. Probability is found by dividing this by the total number of cards, 8. This gets you a fraction of 3/8.
