How do you find the equation of a circle passing through two points?
The y-coordinate of the center of the circle is mx + (f – e). Call this center (p, q). The radius of the circle (r) will be the distance from the center of the circle to either of the two original points. The equation of the circle is (x – p)^2 + (y – q)^2 = r^2.
What is the equation of the circle which passes through the points 3 2 and 2 0 and having its Centre on line 2x y 3 0?
∴ The equation of the circle is x2 + y2 + 3x + 12y + 2 = 0.

How do you find the equation of a circle given coordinates?
The formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle.
How do you find the equation of a circle?
How do you know if a circle passes through the origin?
The equation of a circle with centre at (h, k) and radius equal to a, is (x – h)2 + (y – k)2 = a2. When the centre of the circle coincides with the origin i.e., a2 = h2 + k2. Let O be the origin and C(h, k) be the centre of the circle.
Can a circle pass through 3 points?
The Circle Passes through Three Non-collinear Points. Constituting the equal distance from the centre to all sides of the circle, it is known as the radius of a circle passing through 3 points.
What is A and B in circle equation?
A circle is the set of all points in the plane which maintains a fixed finite distance r from a fixed point O = ( a , b ) O=(a,b) O=(a,b). Here O is called the center, and r is called the radius of that circle.
What is the equation of the circle in standard form with center 1/2 and radius 3?
Radius, r = 3 units. We have to write the equation of the circle. Therefore, the equation of the circle is (x – 2)2 + (y – 1)2 = 9.
