HELP ME WITH THIS MATH QUESTION

Answer 1

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
