Question

what is the arc length ?

Answer 1

315• - 360• = 45•.
It should be 45 degrees. If your looking for the arc that is unshaded.

Answer 2

Answer:

$\large \boxed{\text{43.98 mi}} }$

Step-by-step explanation:

The formula for arc length (s) as a function of the angle (θ) is

s = rθ, where θ is measured in radians.

If θ is measured in degrees, the formula becomes

$s = \dfrac{\pi r \theta }{180}$

Calculation:

$s = \dfrac{\pi \times 8 \times 315}{180} = 14 \pi \approx \textbf{43.98 mi}\\\\\text{The arc length is approximately \large \boxed{\textbf{43.98 mi}} }$
