What is the arc length if $Θ = 6\pi/5$(sorry, dont know how to format that) and the radius is $2$ cm?

  • length of arc= $n/360= 2\pi(r)$ is it $2/360=2\pi(r) 2\pi(180)$?

  • For $\pi$ , just put $ tags around \pi . For a fraction, you can do like you did, or use $ with \frac {}{} , where first you put numerator then denominator – BFD Oct 30 '13 at 23:24

The arc length formula is $L=r\theta$, so the length is $\frac {12\pi}5$ cm.
