I get the same answer. I guess we're both wrong?
Or do they want it reduced to:
8x^2 -6x -5

Length arc AB = 3.14 in
Step-by-step explanation:
Length of arc AB = central angle/360 * 2πr
Central angle = 30°
Radius (r) = 6 in.
Substitute
Length of arc AB = 30/360 * 2*π*6
Length arc AB = 3.14 in. (Nearest tenth)
