    The center of the circle is on the y-axis, so let the coordinates of the center of the circle be (0,a) and the radius is 5, so let the equation of the circle be x 2+(y-a) 2=5 2, substitute the ab coordinates into the equation respectively, and take the common solution to obtain a=6, so that the equation of the circle is x 2+(y-6) 2=25

    The center of the circle is on the y-axis Let the coordinates of the center of the circle be (0,y) according to the equation of the distance from the center of the circle to any point on the circle.

    0-(-3)] square + (y-2) square = (0-3) square + (y-10) square.

    Solving the equation gives us y=6 and the radius is 5 according to the distance between the center of the circle and the point, so the equation for the circle is x-squared + (y-6) squared = 25

    Solution: Let the circular equation be (x) 2+(y-y1) 2=25, pass the points a, b, and substitute y1=

    So the center of the circle is (0,y1).

    Let the center of the circle be (x,0) (x-2) +9=25 x=-2 or 6

    The circular equation is (x+2) +y =25 or (x-6) +y =25

    Let the equation be (x-a) 2+y 2=r 2, then:

    2-a)^2+(-3)^2=5^2

    The solution yields a1=-2 and a2=6

    The equation is (x+2) 2+y 2=25 or (x-6) 2+y 2=25

    The center of the circle is the midpoint of the diameter, and the coordinates of the two points of the diameter (4,0)(0,-6) can be known by using the triangle similarity

    Then the radius r = under the root number (4 squared + 6 squared) 2 = root 13

    Then the circle: (x-2) 2+(y+3) 2=13

    Set the round round fiber hidden pure heart is (carry block x, 0).

    Then because the circle is tangent to the straight line x+2y=0.

    So d=lx+2 0+0l (destroy 1 +2 )=5, so lxl=5 gets x= 5

    Because the circle is on the left side of the y-axis, x=5

    So the center of the circle is (5,0).

    Then the equation for the circle (x-5) +y =5

    Method 1:

    Let the original equation be: (x-a).

    y =r two points can be substituted into the solution of the system of equations.

    Let the equation of the line where ab is located is: y=kx

    m substitutes the two points a and b, and the solution is: k = 1

    m=2 so the straight line ab is: y=x

    The coordinates of the midpoint in 2ab are (0,2).

    Let the line perpendicular to ab be: y=-x

    N substitute (0,2) to get y=-x

    2. This straight line passes through the center of the circle.

    Let y=0x=2, so the coordinates of the center of the circle o are o(2,0).

    r=ao=√(9

    So the original equation is (x-2).

    The length of the line segment AB = root number (.)

    The midpoint d( of the line segment AB is obtained from the midpoint coordinate formula

    Because point d is on the x-axis and the center of the circle is on the x-axis, the center of the circle passing through a and b on the x-axis is d, and the radius is 5;

    The equation for this circle: (x+2) 2+y 2=25

    Center of the circle (a,0).

    r =25, so the rock burn (a-6) +0-3) =25a paragraph letter -12a + 36 + 9 = 25
