- 1. 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 - 2. Multiple Choice
Write the equation of the circle with center C( -5 , 8 ) and radius = 7
( x - 5 )2 + ( y + 8 )2 = 14
( x - 5 )2 + ( y - 8 )2 = 49
( x - 5 )2 + ( y + 8 )2 = 49
( x + 5 )2 + ( y - 8 )2 = 49

- 8. Multiple Choice
What 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 units
Center (4, 3)
Radius = 25 units
Center (-4, -3)
Radius = 25 units
Center (-4, -3)
Radius = 5 units
- 9. Multiple ChoiceWhat is the coordinates of the centre and the radius of the circle with equation:
(x + 2)2 + (y + 5)2 = 16 ?Centre (2,5)
Radius = 16 unitsCentre (2,5)
Radius = 4 unitsCentre (-2,-5)
r = 16 unitsCentre (-2,-5)
Radius = 4 units - 10. Multiple ChoiceWhat is the coordinates of the centre and the radius of the circle with equation:
(x + 3)2 + (y + 1)2 = 22 ?Centre (-3,-1)
Radius = 4 unitsCentre (3,1)
Radius = 2 unitsCentre (-3,-1)
Radius = 2 unitsCentre (3,1)
Radius = 4 units - 11. Multiple ChoiceWhat is the center of the ellipse?(0, 0)(1, 5)(1, 0)(0, 1)
