Question 1
Find the centre and radius of the circle having the equation x
2 + y
2 - 12x + 20y + 15 = 0.
◦ centre (6, 10) and radius
◦ centre (-6, 10) and radius 15
◦ centre (6, -10) and radius 121
◦ centre (6, -10) and radius 11
◦ centre (12, -20) and radius 15
Question 2
Describe the region defined by the pair of inequalities x
2 + y
2 ≤ 9 and x
2 + (y + 3)
2 ≤ 6.
◦ all points that are inside or on both the circle of radius 3 centred at the origin and the circle of radius
centred at (3, 0)
◦ all points that are inside or on both the circle of radius 3 centred at the origin and the circle of radius
centred at (-3, 0)
◦ all points that are inside or on both the circle of radius 3 centred at the origin and the circle of radius
centred at (0, -3)
◦ all points that are inside or on both the circle of radius 9 centred at the origin and the circle of radius 6 centred at (0, -3)
◦ all points that are inside or on both the circle of radius 3 centred at the origin and the circle of radius
centred at (0, 3)
