Question

give the center and radius of the circle described by the equation and graph the equation. use the graph to identify the relations domain and range.

x² + y² = 49

what is the center of the circle?

the circle is centered at the point

(type an ordered pair.)

Explanation:

Step1: Recall the standard form of a circle's equation

The standard form of a circle's equation is \((x - h)^2+(y - k)^2=r^2\), where \((h,k)\) is the center and \(r\) is the radius.

Step2: Rewrite the given equation in standard form

The given equation \(x^{2}+y^{2}=49\) can be written as \((x - 0)^2+(y - 0)^2 = 7^2\).

Answer:

\((0,0)\)
