I am here to fix an error of the previous solution.


<pre>
{{{S}}} = {{{R*theta}}}   (where S is the length of an arc)

Substituting,

{{{1/2}}} = {{{1*theta}}}

{{{theta}}} = {{{1/2}}} {{{rad}}}
</pre>

<U>Notice to the sender</U>: In this context it would be better to formulate the problem like this:


Give the radian measure of the central angle of a unit circle {{{highlight(cross(and))}}} subtended by an arc of {{{highlight(cross(measure))}}} the length 1/2.
