Step-by-step explanation:

<em>I changed my mind. I'll attempt it.</em>

The formula for finding the arc length: $2\pi (r)(\frac{theta}{360} )$

2π(4)(190/360) = 4 2/9π

82% certain the answer you're looking for is 4 2/9π (<em>pi symbol because it asks for it in terms of pi)</em>

Find the sum (pre calc)

Katyanochek1 [597]

$\text{It is a geometric series.}\\\\\text{First term,}~ a = 2\\\\\text{Common ratio,}~ r = \dfrac{-\tfrac 43}2 = -\dfrac 46 = -\dfrac 23\\\\\text{Sum of an infinite geometric series,}\\\\S_{\infty} = \dfrac{a}{1-r}\\\\\\~~~~~=\dfrac{2}{1-\left(- \dfrac 23 \right)}\\\\\\~~~~~=\dfrac{2}{1+ \dfrac 23}\\\\\\~~~~~=\dfrac{2}{\tfrac 53}\\\\\\~~~~~=\dfrac{6}{5}\\\\$
