Find the length of AB
80° arc

Answer:
11.2
Step-by-step explanation:
The formula for an arc length is [tex]\frac{a}{360\\}[/tex]2πr {a=inside angle(in this case 80°) r=radius}
Simplify this formula by dividing the bottom by two and combining pi and r with the top.
[tex]\frac{\pi80times8 }{180}[/tex]
80 times 8 is 640, so
[tex]\frac{640\pi }{180\\}[/tex]
plug 640 times pi into a calculator and divide by 180.
you'll get 11.170107etc
Round your answer to the nearest tenth, and you get;
11.2
Sorry the steps are so confusing!
