1. Find the equation of a circle with radius 5 and center (-3,3).
















2. Find the equation of a circle with radius 8 and center (0,0).

(x - 8)² + y² = 64


x + y = 8


x² + y² = 64


x² + y² = 8





3. Find the equation of a circle with radius 7 and center (12,6).

(x - 12)² + (y - 6)² = 49


(x + 12)² + (y + 6)² = 49


(x - 12)² + (y - 6)² = 7


(x + 12)² + (y + 6)² = 7
