If the radius of the water sprinkler is 30 feet, what is the area the water sprinkle covers?

2826 ft^2

Step-by-step explanation:

If all the water goes inside the circle, then the area sprinkled is

A = pi*r^2, or A = 3.14*(30 ft)^2 = 3.14*(900 ft^2) = 2826 ft^2

correct answer:

b.(19,-2)

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
