The sprinkler is located 20 feet north of the house. If the house is located at the origin, what is the equation for the circle of area that is watered?
-
Radius is 10/2 = 5 feet.
We imagine north - south line to be y-axis and east - west line to be x-axis, and our coordinates are measured in feet.
Then the center of the circle would be (0,20)
Therefore its equation is x^2 + (y-20)^2 = 5^2

(x)^2+(y-20)^2=20^2
