Given:
There is a chord, radius and central angle given
Required:
We need to find the length of chord in terms of r
Explanation:
Use sin formula
[tex]\begin{gathered} sin\frac{\emptyset}{2}=\frac{\frac{c}{2}}{r} \\ \\ sin\frac{\emptyset}{2}=\frac{c}{2r} \\ \\ 2rsin\frac{\emptyset}{2}= \end{gathered}[/tex]c is the length of chord and r be the radius
