Find The Length Of The Arc In Terms Of Pi AB class=

Sagot :

We will determine the arc length as follows:

*First: We transform the angle to radians:

[tex]\alpha=144\cdot\frac{\pi}{180}\Rightarrow\alpha=\frac{4}{5}\pi[/tex]

*Second: We will determine the arc length:

[tex]s=(10)(\frac{4}{5}\pi)\Rightarrow s=8\pi[/tex]

So, the arc length from A to B is 8*pi.
