Find the equation of a circle given its center (h, k) and radius (r). The calculator provides both standard form and general form of the circle equation.
Find the equation of a circle given its center (h, k) and radius (r). The calculator provides both standard form and general form of the circle equation.
x-coordinate of the center
y-coordinate of the center
Radius of the circle
The standard form of a circle equation uses the center (h, k) and radius r. Expanding gives the general form x² + y² + Dx + Ey + F = 0.
How this calculator works
The standard form of a circle equation uses the center (h, k) and radius r. Expanding gives the general form x² + y² + Dx + Ey + F = 0.
