Step-by-step explanation:
Please post a picture of the triangle and the choices.
An even number between 7 and 16 could be 8, 10, 12, or 14. You know they are even number because they always end with a digit of 2, 4, 6, 8, or 0. Also it is divisible by 2. Just draw a number line.<span />
First, find the fraction of the circumference represented by central angle 7pi/8:
7pi/8
--------
2pi
Then find the circumference; it is C = 2 pi r, or 2pi(6), or 12 pi units
Then the arc length is 7pi/8 7
-------- * 12 pi = -------- units, or 21/4 units, or 5 1/4 units.
2pi 16 pi
