Answer 1

Answer:

Arc=4$\pi$

Step-by-step 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$\pi$
