Answer:
The equations describing the area which each tower covers are given as
Tower A : [tex]x^{2} + y^{2} = 16[/tex]
Tower B : [tex](x - 5)^{2} + (y - 4)^{2} = 9[/tex]
Tower C : [tex](x - 4)^{2} + (y + 4)^{2} = 25[/tex]

Tower A at Adele Acres have position co-ordinates as (0,0) and a coverage radius of 4 ml. So, the area which it covers is given by the equation,
[tex]x^{2} + y^{2} = 16[/tex] -------------------------------(1)
Tower B at Brown Lake have position co-ordinates as (5,4) and a coverage radius of 3 ml. So, the area which it covers is given by the equation,
[tex](x - 5)^{2} + (y - 4)^{2} = 9[/tex] -------------------------------(2)
Tower C at Cady City have position co-ordinates as (4,-4) and a coverage radius of 5 ml. So, the area which it covers is given by the equation,
[tex](x - 4)^{2} + (y + 4)^{2} = 25[/tex] -------------------------------(2)
