For a circle of radius 600ft, find in degrees the central angle subtended by an arc length of 1,200ft.
~~~~~~~~~~~~~~~~~~~~~ 

Use the formula for the arc length

    S = r%2Aalpha,


where  r  is the radius of the circle, alpha is the central angle in radians.


From the formula,

    alpha = S%2Fr = 1200%2F600 = 2 radians = 0.63662031 radians = 114.592 degrees.    ANSWER

Solved.
