Y = - 2x and y = x² - 8, this means that:
-2x = x² - 8 → x² + 2x - 8 = 0
Solve this quadratic equation:
x₁ = [-b + √(b² - 4.a.c)]/2a and x₂ = [-b - √(b² - 4.a.c)]/2a
x₁ = [- 2 + √(4+32)]/2 and x₂ = [- 2 - √(4+32)]/2
x₁ = -4 and x₂ = 2 (in the 2nd equation). Now plug in these values in the 1st equation and you will find - 4 and 8

The answer to your question is C
Length of the circumference is 2πr,
corresponding angle is 360°
2πr-360°
x ---150°
x=2πr*150/360=2π*6.48*150/360=17.0 in
