Answer:
Arc=4[tex]\pi[/tex]
Step-by-step explanation:
The formula to get the length of arc is
Arc= degree x [tex]\pi[/tex]/180 x radius
Going by this formula, we can plug in a few numbers:
Arc= 80 x [tex]\pi[/tex]/180 x 9
Since it says to go off of term pi, we can simplify the 80 and the fraction and simplify.
Arc=80[tex]\pi[/tex]/180 x 9
Arc=4[tex]\pi[/tex]/9 x 9
Simplify, the nine cancels out
Arc=4[tex]\pi[/tex]
