Which of the following provides sufficient information to write the equation of any circle? A. the x-intercept B. the y-intercept C. coordinates of the center D. radius and coordinates of the center

The standard equation of the circle may be determined through the expression,

(x - h) ² + (y - k) ² = r²

where h and k are the abscissa and ordinate of the center of the circle, respectively. r, on the other hand is the measure of the radius. Thus, it is important to know the radius and coordinates of the center. The answer is letter D.
