Question 1038799
.
Give the radian measure of the central angle of a circle of radius 8 and subtended by an arc of measure 2. 
Please show me a solution to the problem. Thank you.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~


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

Substituting,

{{{2}}} = {{{8*theta}}}

{{{theta}}} = {{{2/8}}} = {{{1/4}}} {{{rad}}}

<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 circle of radius 8 {{{highlight(cross(and))}}} subtended by an arc of {{{highlight(cross(measure))}}} the length 2.
