Which equations represent circles that hWhich explains how to find the radius of a circle Which equation represents a circle that contains the point (–2, 8) and has a center at (4, 0)? Distance formula: StartRoot (x 2 minus x 1) squared + (y 2 minus y 1) squared EndRoot (x – 4)2 + y2 = 100 (x – 4)2 + y2 = 10 x2 + (y – 4)² = 10 x2 + (y – 4)² = 100whose Which equation represents a circle that contains the point (–2, 8) and has a center at (4, 0)? Distance formula: StartRoot (x 2 minus x 1) squared + (y 2 minus y 1) squared EndRoot (x – 4)2 + y2 = 100 (x – 4)2 + y2 = 10 x2 + (y – 4)² = 10 x2 + (y – 4)² = 100equation is in the form x2 + y2 = z? The radius is the constant term, z. The radius is the constant term, z, divided by 2. The radius is the square root of the constant term, z. The radius is the square of the constant term, z.ave a diameter of 12 units and a center that lies on the y-axis? Select two options. x2 + (y Which equations represent circles that have a diameter of 12 units and a center that lies on the y-axis? Select two options. x2 + (y – 3)2 = 36 x2 + (y – 5)2 = 6 (x – 4)² + y² = 36 (x + 6)² + y² = 144 x2 + (y + 8)2 = 36– 3)2 = 36 x2 + (y – 5)2 = 6 (x – 4)² + y² = 36 (x + 6)² + y² = 144 x2 + (y + 8)2 = 36
