Hi,

Again, we're going to be following the same format we did last time, but the sides of the equation have been swapped. Let's not worry about this, as it doesn't exactly make a difference.

Since 1 is negative, we must add it on both sides.

<em>8 + 1 = 3r - 1 + 1
</em>
<em>9 = 3r
</em>
<em />Now, we have 3 which is multiplying our variable r. The inverse of multiplication is division, so we will divide both sides by 3. This will leave us with our answer.

<em>9 / 3 = 3r / 3
</em>
<em>3 = r </em>or <em>r = 3.
</em>
Hopefully, this helps.

7. The bottom of a circular swimming pool
mote1985 [20]
<h2>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:

Area_{circle}=\pi radius^{2}

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:

diameter=2radius\\\\radius=\frac{diameter}{2}

So,

radius=\frac{36feet}{2}=18feet

Then, calculating the area we have:

Area_{bottom}=\pi radius^{2}=\pi 18ft^{2}=1017.88ft^{2}

Hence, we have that 1017.88 square feet are blue.

Have a nice day!

Find the length of the missing side
Sindrei [870]

Answer:

x = 9.2

Step-by-step explanation:

Use Pythagorean Theroem to find the lenght of x

a^2 + b^2 = c^2

6^2 + 7^2 = x^2

36 + 49 = x^2

85 = x^2

then find the square root of 85 which is 9.2
