Check the picture below. part 1 and 2 are there.

part 3)

$\bf \textit{arc's length}\\\\
s=\cfrac{r\theta \pi }{180}\implies \cfrac{180s}{r\pi }=\theta \qquad 
\begin{cases}
\theta =\textit{angle in degrees}\\
r=radius\\
----------\\
s=12.2\\
r=\sqrt{\frac{315}{\pi }}
\end{cases}
\\\\\\
\cfrac{180\cdot 12.2}{\pi \sqrt{\frac{315}{\pi }}}=\theta \implies 69.8075^o\approx \theta \implies 70^o\approx\theta$

$\bf \textit{area of a sector of a circle}\\\\
A=\cfrac{\theta \pi r^2}{360}\quad 
\begin{cases}
r=\sqrt{\frac{315}{\pi }}\approx 10\\
\theta \approx 70
\end{cases}\implies A=\cfrac{70\cdot \pi \cdot 10^2}{360}$
