Solve the Problem $( x + 7 ) ^ { 2 } + ( y + 6 ) ^ { 2 } = 6.25$

Multiple Choice

Solve the problem.
-A cell tower is a site where antennas, transmitters, and receivers are placed to create a cellular network. Suppose that a cell tower is located at a point A(-7, -6) on a map and its range is 2.5 mi. Write an equation that represents the boundary of the area that can receive a signal from the tower.
Assume that all distances are in miles.

A) $( x + 7 ) ^ { 2 } + ( y + 6 ) ^ { 2 } = 6.25$
B) $( x + 7 ) ^ { 2 } + ( y + 6 ) ^ { 2 } = 2.5$
C) $| x + 7 | + | ( y + 6 ) | = 2.5$
D) $| x - 7 | + | ( y - 6 ) | = 2.5$
