Answer:
Equation of a circle
Step-by-step explanation:
In the two-dimensional Cartesian Plane, we can write an equation representing a circle. This equation is the combination of all points on the circle, which happen to connect. The equation is
(x - h)² + (y - k)² = r²
(
h
,
k)
is the center of the circle, and
r is the radius of the circle.
if h and k equal 0
, we get
[tex]x^{2} +y^{2} =r^{2}[/tex]
This is the equation for a circle of radius r
centered at the origin.
