First, we need to think about what we're actually solving for: the area of the path. To find this, we can find the area of the whole thing, minus the area of the pool.
The diagram would look something like the picture I attached. We know that to find the area of a circle, you do πr^2. The radius is half of the diameter, so halve the diameters:
22/2 = 11 yards
32/2 = 16 yards
Then solve for the area of both circles.
π
π ≈ <span>380.13 (area of the pool)</span>
π
π ≈ <span>804.25 (area of the whole thing)
</span>
Next, subtract the area of the pool from the area of the whole thing to find the area of the walkway:
(area of the walkway)
Finally, divide the area of the walkway by 6 to see how many gallons of paint you'll need:
424.12 ÷ 6 ≈ 70.69
So you'll need 71 gallons of paint!
Hope I helped and let me know if you have any questions :)

Answer:
or
Step-by-step explanation:
Substitution means plugging in one variable's value that consists of the opposite variable. Because is already specified, you can plug it into the second equation's
value. After doing that, it looks like this:
Then you would distribute the across the parentheses next to it, like this:
Then, add like terms, like this:
Then divide both side by to isolate
.
Now, you can plug (
) into either equation, but the first one seems simpler so you would pick that. It would look like this:
Solving would look like this:
So the answer is or
