Circles in the Coordinate Plane Quiz 2023-2024
A low-wattage radio station can be heard only within a certain distance from the station. On the graph below, the circular region represents that part of the city where the station can be heard, and the center of the circle represents the location of the station. Which equation represents the boundary for the region where the station can be heard?
(x + 6)² + (y + 1)² = 16
Write the standard equation for the circle center (-6,-8), that passes through (0,0).
(x + 6)² + (y + 8)² = 100
Write the standard equation for the circle center (-6,7) , r = 9.
(x + 6)² + (y - 7)² = 81
Write the standard equation of the circle in the graph.
(x - 3)² + (y - 2)² = 9
