1. We have to solve for 5 surface faces.
2. Triangle Area Formula=base x height / 2
3. We get 60 as the area when u plug the numbers into the formula.
4. Since there is another triangle in the back it’s also 60 so then it’s 120.
5. Then we do length times width for the two rectangles.
6. When completing the equation you get 130.
7. Since you have another rectangle the same length you add another 130 making it 260.
8. Lastly, the base same thing length times width.
9. The answer for that is 240.
10. Now u add everything 240+260+120=620.

Answer:

The equations describing the area which each tower covers are given as

Tower A : $x^{2} + y^{2} = 16$

Tower B : $(x - 5)^{2} + (y - 4)^{2} = 9$

Tower C : $(x - 4)^{2} + (y + 4)^{2} = 25$

Step-by-step solution:

Cell phone radio towers broadcast a cell phone signal in circular pattern

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,

$x^{2} + y^{2} = 16$ -------------------------------(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,

$(x - 5)^{2} + (y - 4)^{2} = 9$ -------------------------------(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,

$(x - 4)^{2} + (y + 4)^{2} = 25$ -------------------------------(2)
