umka21 [38]

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)

Lynna [10]

Step-by-step explanation:

diameter=

2 \times\pi \times r = 6 \\ r =  \frac{6}{2 \times 3.14}  = 0.955 \\ area = \pi \times  {r}^{2}  = 3.14 \times  {0.955}^{2}  \\  =  2.87\:  {cm}^{2}
