So the question is, a circle PQR has centre - and radius r it is divided into three equal areas by the chords PQ and PR given the angle QPR is X radians find the area of the sector OQR, and deduce the triangle OQR is Sin X = Pi/3 - X
Im kinda confused, mainly about how to sketch this any tips?

Start by realising that the angle QOR is 2X. (angle at centre = 2 x angle at circumference
Really poor sketch addedLast edited by nerak99; 20-05-2016 at 18:45.
