Answer:
7.5π units
Step-by-step explanation:
The length of the arc is calculated as
arc = circumference of circle × fraction of circle
= 2πr × [tex]\frac{270}{360}[/tex]
where r 9s the radius and 270° is the angle subtended at the centre.
arc = 2π × 5 × [tex]\frac{3}4}[/tex]
= 10π × 0.75 = 7.5π units
