Assignment: Circle Equation Applications

1.  On the coordinate plane below, graph and label the coverage circle for towers B and C. Label Dale as the center of tower A’s coverage circle. Assume that each square on the graph represents one mile. Moving in a positive direction on the x-axis shows movement to the east and moving in a positive direction on the y-axis show movement to the north.

2.  Write the general form for a circle that represents the coverage radius for each of the three towers. Hint: Start by writing the standard form equation for each circle and then transforming each equation into general from.
