I'm guessing you're saying that the sprinkler is shooting out 23 ft of water.
This would be the same as the radius of a circle, and we're trying to find the area. Use the formula.

Plug in what we know:


This is what they could be looking for, an exact value. If they want an approximation, we can input 3.14 for Pi:

Answer:
40
Step-by-step explanation:
(6 + 2i)(6 - 2i)=40
Answer:
-8x
Step-by-step explanation:
<h2><u>
Answer:</u></h2>
x = 3
y = -8
<h2><u>
Step-by-step explanation:</u></h2>
x + y = -5
x - y = 11
Since the y's will cancel out, we don't need to modify the two equations in any way.
Now, just add the two equations.
x + x = 2x
y + (-y) = 0
-5 + 11 = 6
2x = 6
Divide by 2.
x = 3
To find y, plug 3 in as "x" in one of the two equations.
3 + y = -5
y = -8
