A circle has a diameter
with endpoints at (10, 8)
and (5, 4). What is the
circumference of this
circle?​

Respuesta :

Answer:

The answer to your question is below

Step-by-step explanation:

Data

A (10, 8)

B (5, 4)

Process

1.- Find the length of the radius

   d = [tex]\sqrt{(5 - 10)^{2} + (4 - 8)^{2}}[/tex]

   d = [tex]\sqrt{5^{2} + 4^{2}}[/tex]

   d = [tex]\sqrt{25 + 16} = \sqrt{41}[/tex]

   radius = [tex]\sqrt{41} / 2[/tex]

2.- Find the center

 Xm = [tex]\frac{10 + 5}{2}[/tex]

 Xm = [tex]\frac{15}{2}[/tex]

 Ym = [tex]\frac{8 + 4}{2}[/tex]

Ym = [tex]\frac{12}{2} = 6[/tex]

Center = (15/2 , 6)

3.- Write the equation of the circle

     (x - 15/2)² + (y - 6)² = [tex]\frac{41}{4}[/tex]
