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

If 1/4x - 1/4 = 2 then 2 + 1/4 = 1/4x.
so 3/4 = 1/4x
3/4 is equal to 1/1.33 (reduce by dividing both numerator and denominator by 3)
so 4 x ? = 1.33. 1.33 / 4 = 0.3325
so (if you're solving for x) I believe the answer is x = 0.3325
