Answer:

Arc=4
$\pi$

Explanation:

The formula to get the length of arc is

Arc= degree x
$\pi$ /180 x radius

Going by this formula, we can plug in a few numbers:

Arc= 80 x
$\pi$ /180 x 9

Since it says to go off of term pi, we can simplify the 80 and the fraction and simplify.

Arc=80
$\pi$ /180 x 9

Arc=4
$\pi$ /9 x 9

Simplify, the nine cancels out

Arc=4
$\pi$
