Frequently Asked Questions
What is the standard equation of a circle centered at (2, 3) with radius 3?
The standard equation is (x - 2) squared plus (y - 3) squared equals 9.
How is the general form found from the standard form?
D equals negative 2 times the center x-coordinate, E equals negative 2 times the center y-coordinate, and F equals the center x-coordinate squared plus the center y-coordinate squared minus the radius squared.
What other properties does this calculator find besides the equation?
It also finds the circle area and circumference directly from the radius, alongside both equation forms.
