Write standard equation of a circle calculator

The equation of a circle written in the form (x−h)2+(y−k)2=r2 where (h,k) is the center and r is the radius. The circle centered at the origin with radius 1; its equation is x2+y2=1.

The standard form of the equation of a circle is (x−A)² + (y−B)² = C. We can write the general form of the circle equation to the standard form by calculating the unknowns A, B, and C from the general equation's parameters D, E, and F. Luckily, that math is easy! C = A² + B² − F.

The equation of a circle is (x-4)² + (y-6)² = 8 . You can find this equation by using the following steps: Find the x-coordinate (h) & y-coordinate (k) of the center of the circle by taking the summation of x-coordinates & y-coordinates of the endpoints of the diameter respectively and dividing by 2 .

To find the equation of a circle when you know the radius and centre, use the formula ( x − a ) 2 + ( y − b ) 2 = r 2 , where represents the centre of the circle, and is the radius.
