A bicycle goes through a circular arc of the highway. If the radius of the curve is 1,250 ft. Find the central angle in degrees, then it subtends a circular arc of the highway 116.5 ft.

Answer 1

Angle = arc length divided by radius = 116.5/1250 =0 .0932 radians = = about 0.03pi radians = about half a degree,

or 32 minutes, where one degree=60 minutes
