The center of a circle is at (5, –4). A point on the circle is located at (12, –4). What is the approximate circumference of the circle?

Respuesta :

Answer:

43.98 approximately

Step-by-step explanation:

radius = [tex]\sqrt{ (5 - 12)^{2} + (-4+4)^{2} }[/tex]

          = [tex]\sqrt{(-7)^{2} + 0^{2} }[/tex]

          = [tex]\sqrt{49} = 7[/tex]

diameter = 14

Circumference = diameter x pi

                         = 14π = 43.98 approximately
