Answer: JM = 12.9mi
Step-by-step explanation:
First let’s find the perimeter of the circle:
Form: P = d x pi
d = 16.4
pi = 3.14
P = 16.4 x 3.14
P = 51.496mi
Find arc JM:
M is the midpoint of JK
And MO perpendicular JK
Thus, JM = 1/4P
But P = 51.496
=> JM = 51.496/4
JM = 12.874
Round to the nearest tenth:
12.874 = 12.9
Therefore, JM = 12.9mi
