x 2 + y 2 = 20

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 = 2 √ 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: 2 √ 5
