Answer:
A
Step-by-step explanation:
check this link:
x2+y2=0.25
This is the form of a circle. Use this form to determine the center and radius of the circle.
(x−h)2+(y−k)2=r2
Match the values in this circle to those of the standard form. The variable (r) represents the radius of the circle, (h) represents the x-offset from the origin, and (k) represents the y-offset from origin.
r=0.5
h=0
k=0
The center of the circle is found at
(h,k).
Center: (0,0)
These values represent the important values for graphing and analyzing a circle.
Center: (0,0)
Radius: 0.5
