The equation of a circle in general form is x2+y2+22x+14y−55=0 . what is the equation of the circle in standard form?
(x+11)2+(y+7)2=121

(x+11)2+(y+7)2=225

(x+22)2+(y+14)2=225

(x+22)2+(y+14)2=121

Step-by-step explanation:

Since, the standard form of the circle is,

(x-h)² + (y-k)² = r²

Where (h,k) is the center of the circle and r be the radius of the circle.

Here, the given general form of the circle is,

Which is the required standard form of the circle.
