Name: Lorie Ann HunterDate: School: Facilitator: 10.07 Circles in the Coordinate PlaneIn problems 1-3, determine the center and radius of the circle with the equation given.1.(x – 3)2+ (y – 3)2= 25Center: (3,3)Radius =52.(x – 1)2+ (y + 2)2= 9Center: (1,-2)Radius =33.(x + 3)2+ (y + 4)2= 1Center: (-3,-4Radius:1For problems 4-7, write the equation for circle O based on the given information.
8.Graph the equation (x – 1)2+ (y + 3)2= 9. Drag the center to the appropriate location andlabel it. Then, drag and adjust the circle. (Hint – use the one of the corners to re-size thecircle without changing its shape.) Place the radius (adjusting its length) as well.
)
9.Graph the equation x2+ y2= 25. Drag the center to the appropriate location and label it.
