Find the center and radius of a circle, given the equation of the circle. • Finding the center and radius may involve completing the square. The completing the square expectation for Geometry follows Algebra I: leading coefficients will be 1 (after possible removal of GCF) and the coefficients of the linear terms will be even.
The standard equation of a circle with center (h, k) and radius = r is Match each graph with its equation. Give the radius and coordinates of the center of the circle with the given equation.
