Find the center-radius form of the circle with center { 1:1, 5} that passes through the point [ 5,5}. The center-radius form of the equation of the circle is E. {Type an equation. Simplify your answer.) If the coordinates of the endpoints of a diameter of the circle are known, the equation cf a circle can be found. First. nd the midpoint of the diameter, which is the center of the circle. Then nd the radius, which is the distance from the center to either endpoint of the diameter. Finally use the centerradius form to nd the equation. Find the center-radius form for the circle having the endpoints [518} and ( 1,3} of a diameter. E (Type an equation.)
