(x-3)2+(y+5)2=64

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=8

h=3

k=-5

The center of the circle is found at (h,k).

Center: (3,-5)

These values represent the important values for graphing and analyzing a circle.

Center: (3,-5)

Radius: 8
