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
(Please put this into the Math section not the Off topic one...)
sorry caps.. :I
but really, what diagram?
Arc PQ = radius * θ
Arc PQ = 18 m * (2pi /3) = 36pi/3 m = 12 pi (m )
