The length of the line segment AB where A(x_A;\ y_A) and B(x_B;\ y_B)

|AB|=\sqrt{(x_B-x_A)^2+(y_B-y_A)^2}

We have: A(1;\ 6);\ B(11;-4)

subtitute

|AB|=\sqrt{(1-11)^2+(6-(-4))^2}=\sqrt{(-10)^2+10^2}=\sqrt{100+100}\\\\=\sqrt{100\cdot2}=\sqrt{100}\cdot\sqrt2=10\sqrt2\approx14.1

Answer: b. 14.1

Answer:

Step-by-step explanation:

We can use the slope formula

m = (y2-y1)/(x2-x1)

    = (5-8)/(-8 - -5)

    = -3/(-8+5)

    = -3/-3

   = 1

➷ The formula to calculate the circumference is \pi d

d is the diameter (double the radius)

Substitute the values in:

Circumference = (3.14)(3 x 2)

Circumference = 18.84

It would be option D. 18.84 m
