Answer 1

12.9 miles

Explanation:

Formula: (x/360)×dπ(circumference)

90/360=1/4

1/4×16.4π

1/4×51.496

12.874

Answer 2

`m JM=90 =\Theta`

`Radius=dimeter/2=16.4/2`

`\longrightarrowr=8.2`

The length of arc JM=

`=(\Theta )/(360) *\pi r`

`=(90)/(360) *2*\ 3.14* 8.2`

`=12.874`

`\approx 12.9 \; miles`
