Transcript text: Given the center and radius, write the standard equation for the circle.
Center: $(-5,2)$ Radius: 6
$(x+5)^{2}+(y-2)^{2}=6$
$(x+5)^{2}+(y-2)^{2}=6^{2}$
$(x-5)^{2}+(y-2)^{2}=6^{2}$
$(x+5)^{2}+(y+2)^{2}=6^{2}$
Solution
Solution Steps
To write the standard equation of a circle given its center and radius, use the formula \((x - h)^2 + (y - k)^2 = r^2\), where \((h, k)\) is the center and \(r\) is the radius. Substitute the given center \((-5, 2)\) and radius \(6\) into this formula to find the correct equation.
Step 1: Identify the Center and Radius
The center of the circle is given as \((-5, 2)\) and the radius is \(6\).
Step 2: Apply the Standard Equation of a Circle
The standard equation of a circle is given by:
\[
(x - h)^2 + (y - k)^2 = r^2
\]
where \((h, k)\) is the center and \(r\) is the radius.
Step 3: Substitute the Values
Substituting the values of the center and radius into the equation:
