For this case we have that by definition, the arc length of a circle is given by:


AL = \frac {x * 2 \pi * r} {360}

Where:

x: Represents the angle between JM. According to the figure we have that x = 90 degrees.


r = \frac {16.4} {2} = 8.2

So:


AL = \frac {90 * 2 \pi * 8.2} {360}\\AL = \frac {90 * 2 * 3.14 * 8.2} {360}\\AL = 12.874

Rounding:


AL = 12.9 miles

Answer:

12.9 miles
