Skill #9 Circle Equations (RED)

What would be the correct equation for this circle?

• 
  

  (x+4)² + (y+4)² = 2²

• (x-4)² + (y-4)² = 2²

If the center of a circle is at (-4, -2) and the radius is 1, what is the equation of the circle?

• (x-4)² + (y-2)² = 1²

• (x+4)² + (y-2)² = 1²

• (x-4)² + (y+2)² = 1²

• (x+4)² + (y+2)² = 1²

For a circle with a center at (3, -4) and a radius of 3, what is the equation?

• (x+3)² + (y-4)² = 3²

• (x-3)² + (y+4)² = 3²

What would be the equation of a circle with a radius of 5, and centered at (4, -6)?

• (x+4)² + (y-6)² = 5²

• (x-4)² + (y+6)² = 5²
