    Maths question help please, with working out in radians!

    An oar of length L metres has the tips of its handle and its blade at A and B respectively. It is pivoted at P a quarter of the way from A to B.

    During a stroke, A travels along an arc of a circle of length L/3 m.

    a) Find the area of the sector swept out by PB during this stroke.

    The oar is moved so that P is now three-tenths of the way from A to B, and the angle turned by the oar in a stroke is not changed.

    b) Find the length of the arc along which B travels during a stroke.

    Please post your attempt or give ideas about what can e done or what exactly you're stuck with.

    Also please make your titles a bit more descriptive in the future - e.g. 'maths AS radians'
