• Question: The equation of a circle is given below: (x + )² + y² = 1 Find the center and radius of the circle. How do you write an equation of a circle in standard form?•A line segment from one point on the circle to another point on the circle that passes through the center is twice the radius in length. This line segment is called the diameter of the circle. A circle can be represented by two different forms of equations, the general form and the center-radius form. •For example: Given- write the equation x 2 + y 2 - 4x + 6y +4 =0 into the standard form for the circle, and find its radius. You can follow the steps given below: The standard form of a circle is (x - h) 2 + (y - b) 2 = r 2 , where (h, k) is the center and r is the radius of a circle.
