    A cyclist travels from A to B along the arc of a circle of radius 25 m as shown.

    Calculate (i) the distance travelled, (ii) the displacement undergone, by the cyclist.

      I'm guessing this answer will be too late and not useful but I'm going to fire away anyways

      The distance travelled is simply 1/4 of the circumference of a 25m which can be found using 1/4 x 2x3.14x25 = 39.26990817 = Approximately 39.27m

      The displacement is the straight line distance from the A to B. We can find this using Pythagoras theorem

      Root(25squared plus 25squared) = 35.35533906m = approx 35.36m

      I'm in 6th year myself and this was a simple question...

      i later found the rest of the solutions here
