What Equation of a Circle with Diameter Endpoints Calculator does

This calculator determines the equation of a circle when given the coordinates of the diameter's two endpoints. It computes the center (midpoint) and radius (half the distance between the points), then outputs the circle's equation in standard form, as well as general and parametric forms. In addition to the equation, the tool provides derived values for the circle's diameter, area, and circumference, offering a complete geometric profile from just two input points.

Questions

Equation of a Circle with Diameter Endpoints Calculator FAQ

Can I use this calculator if I only know the circle's radius and one endpoint of the diameter?
The tool outputs the equation in standard form ( (x - h)^2 + (y - k)^2 = r^2 ), general form ( Ax^2 + Ay^2 + Bx + Cy + D = 0 ), and parametric form ( x = h + r*cos(t), y = k + r*sin(t) ), where (h, k) is the center and r is the radius.
Does the calculator show the steps it uses to find the equation?
The calculator provides the derived radius, diameter, area, and circumference alongside the equation, giving a full set of circle measurements from the two diameter endpoints.
