(h,k) is a point on the circle.
(h,k) is a point that we guess and find
(h,k) is the distance of the circle
- 2. Multiple ChoiceIn the equation (x-3)2+(y+4)2=121, the radius of the circle is2421112122
- 3. Multiple ChoiceWhat is the equation of a circle with radius 2 and center (3, 4)?(x+3)2 + (y+4)2 = 2(x-3)2 + (y-4)2 = 2(x+3)2 + (y+4)2 = 4(x-3)2 + (y-4)2 = 4
- 4. Multiple Choice
What is the equation of the circle?(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 - 5. Multiple ChoiceWhat are the coordinates of the center and the radius of the circle with equation:
(x - 4)2 + (y - 3)2 = 25 ?Center (4,3)
Radius = 5 unitsCenter (4,3)
Radius = 25 unitsCenter (-4,-3)
Radius = 25 unitsCenter (-4,-3)
Radius = 5 units - 6. Multiple ChoiceIn the equation (x-3)2+(y-2)2=16, the center of the circle is...(3,2)(-3, -2)(-2, -3)(2, 3)
- 7. Multiple Choice
What is the equation of the circle.
(x - 3)2 + (y + 4)2 = 9
(x - 3)2 + (y + 4)2 = 3
x2 + y2 = 9
(x - 1)2 + (y + 1)2 = 7
- 8. Multiple ChoiceSee PictureABC

- 10. Multiple Choice
Center is at (-3, 1) and radius is 3.
(x + 3)2 + (y - 1)2 = 9
(x - 3)2 + (y + 1)2 = 9
(x - 3)2 + (y + 1)2 = 3
(x + 3)2 + (y - 1)2 = 3
- 11. Multiple ChoiceWhat is the equation of the circle, with centre (3,8) and radius 4 units?(x - 3)2 + (y - 8)2 = 4(x - 3)2 + (y - 8)2 = 16(x + 3)2 + (y + 8)2 = 16(x + 3)2 + (y + 8)2 = 4
- 12. Multiple ChoiceWhat is the center and radius of this circle?
(x + 3)2 + (y + 7)2 = 4Center: (-3, -7)
radius = 2Center: (3, 7)
radius = 4Center: (-3, -7)
radius = 4Center: (-3, 7)
radius = 2 - 13. Multiple Choice
The diameter of a circle has length 12. The center is at (-5, 2). Give the equation of the circle.
(x + 5)2 + (y - 2)2 = 144
(x - 5)2 + (y + 2)2 = 36
(x + 5)2 + (y - 2)2 = 36
(x - 5)2 + (y + 2)2 = 12
