Circle: General Equation - Softschools.com
WebIn general form, A, B and C do not tell us anything about the circle. In standard form, • a and b tells us that (a, b) are the Cartesian coordinates of the center of the circle. • r tells … Web2. =. r. 2. When the circle center is elsewhere, we need a more general form. We add two new variables h and k that are the coordinates of the circle center point: (x-h) 2 + (y-k) 2 = r 2. We subtract these from x and y in the equation to translate ("move") the center back to the origin. If you compare the two formulae, you will see that the ... kitchen grocery diaries
