The standard equation of a circle, with center in (a,b) and radius r, is: (x-a)2 + (y-b)2 = r2
(x - A)2 + (y - B)2 = R2 The center of the circle is the point (A, B) . The circle's radius is ' R '.
The answer is indeterminate. For example, if the equation is of the form x2 - 2ax + y2 - 2by = 25, all that can be said of the radius of the circle is that it is greater than 5.
The equation for a circle is generally written in the form (x+a)^2+(y+b)^2 = r^2Remember, for the centres for the x and y value, they go in the opposite direction of the rule.So:if the centre is (-2,-4), the equation of the circle is (x+2)^2+(y+4)^2=9
There are different standard forms for different things. There is a standard form for scientific notation. There is a standard form for the equation of a line, circle, ellipse, hyperbola and so on.

The Pythagorean theorem is used to develop the equation of the circle. This is because a triangle can be drawn with the radius and any other adjacent line in the circle.
Area of a circle = pi*radius squared Circumference of a circle = 2*pi*radius or diameter*pi

(x - A)2 + (y - B)2 = R2 The center of the circle is the point (A, B) . The circle's radius is ' R '.
There are probably several ways to approach it; one general equation for the circle is: (x - a)2 + (y - b)2 = r2 This describes a circle with center at coordinates (a, b), and with a radius of r.
If a = b then it is a circle; otherwise it is an ellipse.
The answer is indeterminate. For example, if the equation is of the form x2 - 2ax + y2 - 2by = 25, all that can be said of the radius of the circle is that it is greater than 5.
I'm happy to help you check! Please provide me with the equation you are referencing so I can assist you further.
