Question 1192202
.
For a circle of radius 600ft, find in degrees the central angle subtended by an arc length of 1,200ft.
~~~~~~~~~~~~~~~~~~~~~


<pre>
Use the formula for the arc length

    S = {{{r*alpha}}},


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


From the formula,

    {{{alpha}}} = {{{S/r}}} = {{{1200/600}}} = 2 radians = 0.63662031 radians = 114.592 degrees.    <U>ANSWER</U>
