    does anyone know how you'd do this question 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.

    Draw out the scenario.
