The radius is 32 units.

The radius is 16 units.

The radius is 8 units.

The radius is 4 units.

$$\left(5,\ 3\right)$$  

$$\left(5,\ -3\right)$$  

$$\left(-5,\ 3\right)$$  

$$\left(-5,\ -3\right)$$  

$$\left(x+8\right)^2+\left(y-4\right)^2=36$$

$$\left(x-2\right)^2+\left(y+14\right)^2=144$$

$$x^2+y^2=36$$

$$x^2+y^2=144$$

$$\left(x+6\right)^2+\left(y+6\right)^2=24$$

(x+1)²+(y+1)²=9

x²+y²=9

x²+y²=6

x²+y²=3

(x - 3)² + (y + 4)² = 9

(x - 3)² + (y + 4)² = 3

x² + y² = 9

(x - 1)² + (y + 1)² = 7

Center (4,3)

Radius = 5 units

Center (4,3)

Radius = 25 units

Center (-4,-3)

Radius = 25 units

Center (-4,-3)

Radius = 5 units

(x+1)² + (y +1)² = 3

(x+1)² + (y -1)² = 3

(x+1)² + (y +1)² = 9

(x-1)² + (y -1)² = 9
