Identifying the Center & Radius of a Circle

100

(x - 4)² + (y + 1)² = 36

Center: (4, -1)

Radius: 6

200

(x + 2)² + (y + 5)² = 81

Center: (-2, -5)

Radius: 9

300

x² + (y - 6)² = 100

Center: (0, 6)

Radius: 10

400

(x + 3)² + (y - 6)² = 25

Center: (-3, 6)

Radius: 5

500

(x + 2)² + (y + 3)² = 49

Center: (-2, -3)

Radius: 7

Completing the Square to find the Center and Radius of a Circle

100

x²+ 4x + y² - 4y -1 =0

Center= (-2,2)  Radius= 3

200

x² + y² + 8y -9 =0

Center = (0,-4)  Radius = 5

300

x² + 2x + y² + 4y =11

Center = (-1,-2)  Radius = 4

400

x²+2x+6y+y=15

 Center= (-1,-3)  Radius= 5

500

10x+x²+y²+28y=4

Center= (-5,-14)  Radius= 15
