Circle Equation Calculator Find the equation of the circle withcenter (h,k) = (0,0) and radius r = 3
Standard Circle Equation:
(x - h)2 + (y - k)2 = r2Plugging in our numbers, we get:
(x - 0)2 + (y - 0)2 = 32(x - 0)2 + (y - 0)2 = 9
General form of circle equation
Center (h, k) = (0, 0) and r = r = 3:Expand the standard form
x2 + y2 - 2hx - 2ky + h2 + k2 - r2 = 0Plugg in our values for h,k, and r:
x2 + y2 - 2(0)x - 2(0)y + 02 + 02 - 32 = 0x2 + y2 - 9 = 0
Combine our constants
x2 + y2 - 9 = 0x2 + y2 - 9 = 0

What is the Answer?
x2 + y2 - 9 = 0
How does the Circle Equation Calculator work?
Free Circle Equation Calculator - This calculates the standard equation of a circle and general equation of a circle from the following given items:
* A center (h,k) and a radius r
* A diameter A(a1,a2) and B(b1,b2)
This also allows you to enter a standard or general form equation so that the center (h,k) and radius r can be determined.
This calculator has 8 inputs.
