Provided the following data:
[tex]\theta=135º=2.36\text{ }rad[/tex]
and r = 7 inches, then we can calculate the length of the arc using the following equation:
[tex]s=\theta\times r[/tex]
Where s represents the length of the arc. Thus:
[tex]s=\theta\times r=2.36\times7\text{ }in=16.49\text{ }in=\frac{21\pi}{4}in[/tex]
So the answer is option c.
