The general form for the equation of a circle is ( x − h ) 2 + ( y − k ) 2 = R 2 , but since our circle is centered at the origin we have both h = 0 and k = 0. This allows us to simplify the equation of the circle to x 2 + y 2 = R 2 .
K is the number next to y. So we have y minus four we're going to switch negative four to positiveMoreK is the number next to y. So we have y minus four we're going to switch negative four to positive four so k is four thus the center of the circle. Is three comma four.
The equation of a circle of radius r and centre the origin is x2 + y2 = r2 .
The equation of a circle of radius r and centre the origin is x2 + y2 = r2 .
What is the General Equation of Circle? The general form of the equation of circle is: x2 + y2 + 2gx + 2fy + c = 0. This general form of the equation of circle has a center of (-g, -f), and the radius of the circle is r = √g2+f2−c g 2 + f 2 − c .
What is the general form of the equation of a circle with center at (a, b) and radius of length m? Summary: The general form of the equation of a circle with center at (a, b) and radius of length m is x2 + y2 - 2ax - 2by + (a2 + b2 - m2) = 0.

The general form for the equation of a circle is ( x − h ) 2 + ( y − k ) 2 = R 2 , but since our circle is centered at the origin we have both h = 0 and k = 0. This allows us to simplify the equation of the circle to x 2 + y 2 = R 2 .
Solution: The equation of a circle is given by (x−x1)2+(y−y1)2=r2 ( x − x 1 ) 2 + ( y − y 1 ) 2 = r 2 . If center is at origin, then x1 x 1 = 0 and y1 y 1 = 0. Answer: The equation of the circle if its center is at origin is x2+ y2= r2.
Center of Circle Examples Solution: The center of the circle equation is (x - h)2 + (y - k)2 = r2. The given values are: coordinates of the center (h, k) are (0, 0), and the radius (r) = 5 units. Substituting the values of h, k, and r in the equation, we get, (x - 0)2 + (y - 0)2 = 52.
