General form for that one is :X²+Y²+2ax-2ay+a²=0
just substitute the values then u will get the required ans.
The equation of circle of radius 5 units touches the coordinates axes ...
To find the equation of a circle that touches the coordinate axes in the second quadrant, we need to find the center of the circle. Since the circle touches the x-axis and y-axis, the center must lie on both axes.
Let (h, k) be the center of the circle. Since the circle touches the x-axis, the distance from the center to the x-axis is equal to the radius (5 units). This means that the y-coordinate of the center is 5 units.
Since the circle touches the y-axis, the distance from the center to the y-axis is equal to the radius (5 units). This means that the x-coordinate of the center is -5 units.
So, the center of the circle is (-5, 5).
The equation of a circle with center (h, k) and radius r is (x - h)^2 + (y - k)^2 = r^2.
Substituting the values, we have (x - (-5))^2 + (y - 5)^2 = 5^2.
Simplifying, we get (x + 5)^2 + (y - 5)^2 = 25.
So, the equation of the circle is (x + 5)^2 + (y - 5)^2 = 25.
