The standard equation the circle is given by: (x-xo) ^ 2 + (y-yo) ^ 2 = r ^ 2 Where, (xo, yo): coordinates of the center of the circle r: radius of the circle Substituting values we have: (x - (- 2)) ^ 2 + (y-1) ^ 2 = (4/2) ^ 2 Rewriting: (x + 2) ^ 2 + (y-1) ^ 2 = 4 Answer: An equation that represents the sunflower is: (x + 2) ^ 2 + (y-1) ^ 2 = 4
