Question 1105943
.
Find the number of radians in the central angle that subtends an arc of 6cm on a circle of diameter 5m. Please help me.
~~~~~~~~~~~~~~~~~


<pre>
{{{r*alpha}}} = {{{S}}},


where r is the circle's radius, {{{alpha}}} is the central angle in radians, and S is the arc's length.


Which gives you  {{{alpha}}} = {{{S/r}}} = {{{6/250}}} radians.


Here 6 = 6 cm is the given length of the arc, and 250 = 250 cm = 2.5 m is the circle's radius.
