the diagram shows a sector OPQ of a circle with centre O. the radius of the circle is 18m and the angle POQ is 2π / 3 radians. 

a) find the length of the arc PQ, giving the answer as a multiple of π

Arc PQ   =  radius * θ

 

Arc PQ  = 18 m * (2pi /3)   =   36pi/3 m =   12 pi  (m ) 

 

 

cool cool cool
