Find the length of the arc shown in red. Leave your answer in terms of PI
simplify your answer
_________________________________
Length of the arc = 2Pi r α / 360
α = 180º - 60º = 120º
Length of the arc = 2r Pi α / 360
Replacing 2r= 48 ft
α = 120º
Length of the arc = Pi *120* 48 / 360
Length of the arc = 16 Pi
