x^2+y^2=121
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=r^2
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=11
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: 11
