Step-by-step explanation:

if angle \theta is in radians,then

\theta=l/r

where l= arc length

r=radius of circle.

$\theta=\frac{l}{r}\\or\\l=r \theta\\180^\circ=\pi ~radians\\95^\circ=\frac{\pi \times 95}{180}$

$l=8 \times \frac{95 \pi}{180} =\frac{760 \pi}{180}=\frac{76 \pi}{18}=\frac{38 \pi}{9}$

$l\approx\frac{38 \times 3.14}{9}\approx 13.26~in$

if π=3.4

$l=\frac{38 \times 3.4}{9}\approx 14.36~in$

Convert each fraction to decimal:-

3/5
3 ÷ 5 = 0.6

7/8
7 ÷ 8 = 0.875

5/6
5 ÷ 6 = 0.8333 ≈ 0.83

least to greatest:-

0.6 < 0.83 < 0.875
3/5 < 5/6 < 7/8
