- 1. Multiple Choice
Which of the following is the standard equation of the circle given the conditions: center at the origin with radius 4
x2 + y2 = 4
x2 + y2 = 8
x2 + y2 = 16
x2 + y2 = 64
- 2. Multiple Choice
Which of the following is the standard equation of the circle given the conditions: center at (-4, 3) and radius at √7
(x + 4)2 + (y - 3)2 = √7
(x + 4)2 + (y - 3)2 = 7
(x - 4)2 + (y + 3)2 = √7
(x - 4)2 + (y + 3)2 = 7
- 3. Multiple Choice
What is the equation of the given circle?
(x + 3)2 + (y + 1)2 = 16
(x + 3)2 + (y + 1)2 = 25
(x - 3)2 + (y - 1)2 = 16
(x - 3)2 + (y - 1)2 = 25
- 4. Multiple Choice
What is the equation of circle A?
(x + 2)2 + (y + 1)2 = 16
(x + 2)2 + (y + 3)2 = 16
(x - 6)2 + (y - 5)2 = 16
(x - 6)2 + (y + 2)2 = 16
- 5. Multiple Choice
What is the equation of Circle B?
(x - 3)2 + (y - 2)2 = 9
x2 + (y - 1)2 = 9
(x + 5)2 + (y + 5)2 = 9
(x + 4)2 + (y + 2)2 = 9
- 6. Multiple Choice
Which of the following is the equation of the circle having these conditions: circle at (5, -6) and tangent to the y-axis
(x + 5)2 + (y - 6)2 = 36
(x - 5)2 + (y + 6)2 = 36
(x - 5)2 + (y + 6)2 = 25
(x + 5)2 + (y - 6)2 = 25
- 7. Multiple Choice
Which of the following is the equation of the circle having these conditions: center at (5, -6) and tangent to the x-axis
(x + 5)2 + (y - 6)2 = 36
(x - 5)2 + (y + 6)2 = 25
(x - 5)2 + (y + 6)2 = 36
(x + 5)2 + (y - 6)2 = 25
- 8. Multiple Choice
Which of the following is the equation of the circle having these conditions: it has a diameter with endpoints A(-1,4) and B(4,2).
(x - 3/2)2 + (y - 3)2 = 29/4
(x - 3/2)2 + (y - 3)2 = 16/3
(x - 3/2)2 + (y - 3)2 = 6/5
(x - 3/2)2 + (y - 3)2 = 31/2
- 9. Multiple Choice
