The circle below is centered at the origin, and the length of its radius is 7. What is the circle's equation. A. 7x+7y=49. B. x^
Scilla [17]
Equation of a circle is: <span>(x−h<span>)2</span>+(y−k<span>)2</span>=<span>r2</span></span> h is the x-coordinate of the center and k is the y-coordinate of the center. Even though the formula has minus signs, those are positive numbers. If there were plus signs in there, the numbers h and k would actually be negative. Now since you're centered at the origin, that means h and k are 0, so you'd just have this: <span><span>x2</span>+<span>y2</span>=<span>r2</span></span><span> Now since your radius is 7, just square it and replace r^2 woth that value :)</span>
