MathConvert the general form of a circle equation into standard form and find the circle center, radius, and properties.
Radius
The radius of the circle
Center x-coordinate
2.0000
The x-coordinate of the circle center
Center y-coordinate
3.0000
The y-coordinate of the circle center
Standard form equation

Frequently Asked Questions
What is the general form of a circle equation?
The general form is x squared plus y squared plus D x plus E y plus F equals 0, where D, E, and F are known coefficients.
What is the standard form for D = -4, E = -6, F = 4?
This gives center (2, 3) and radius 3, so the standard form is (x - 2) squared plus (y - 3) squared equals 9.
How is the radius found from the general form coefficients?
The radius equals the square root of D over 2 squared, plus E over 2 squared, minus F.
