If a playground swing is 8 feet long and it's rider swings through a distance of 9.5 feet, what angle does the swing travel through?

working on degrees, radians, angles, sin, cosine, tangent

Andrew M.

One could actually work this as a proportion.
The circumference of the circle inscribed by the swing if it took a full 360o turn is
πd = 8π ≅ 25.133 ft ... That is the distance the swing travels in 360 degrees.
 
9.5 ft is to x degrees as 25.133 ft is to 360 degrees
 
9.5 ft/xo = 25.133 ft/360o
 
x = 9.5(360)/15/133 ≅ 136.1 degrees

8 ft is the radius, not the diameter.
