Answer:
arc ≈ 5.5 units
Step-by-step explanation:
The arc of the circle is calculated as
arc = circumference of circle × fraction of circle
= 2πr × [tex]\frac{\frac{\pi }{2} }{2\pi }[/tex] ( r is the radius )
= 2π × 3.5 × [tex]\frac{1}{4}[/tex]
= [tex]\frac{7\pi }{4}[/tex]
≈ 5.5 ( to the nearest tenth )
