How To Use Circle Equations In Coordinate Geometry Dummies Circle centered at the origin. a circle centered at the origin has a centre at (0, 0). if it has a radius r, the equation is: (x − 0) 2 (y − 0) 2 = r 2. x2 y2 = r2. this is the equation for a circle centered at the origin. this page was written by stephen clarke. Coordinate geometry circle, tangents : c2 edexcel january 2011 q9 example: the points a and b have coordinate ( 2,11) and (8,11) respectively? given that ab is a diameter of circle c. (a) show that the centre of c has coordinates (3,6). (b) find an equation for c. (c) verify that the point (10,7) lies on c. The standard equation of a circle centered about the origin is x 2 y 2 = r 2. we can see this by plugging (0, 0) in for (h, k) in the standard equation of a circle. we can also derive this equation as follows. given that point (x, y) lies on a circle with radius r centered at the origin of the coordinate plane, it forms a right triangle with. X 2 y 2 = r 2. where x,y are the coordinates of each point and r is the radius of the circle. what this means is that for any point on the circle, the above equation will be true, and for all other points it will not. this is simply a result of the pythagorean theorem. in the figure above, you will see a right triangle.

The graph of an equation of the form ( x − a) 2 ( y − b) 2 = r2 is a circle with its center at the point ( a, b) and with radius r. this video looks at using equations of circles to find the center and the radius of a circle to graph it, as well as, writing an equation for a circle, given the center and radius, or a point on the circle. The formula is $$(x h)^2 (y k)^2 =r^2 $$. h and k are the x and y coordinates of the center of the circle $$(x 9)^2 (y 6)^2 =100 $$ is a circle centered at (9, 6) with a radius of 10.
