    Geo/trig Problem.

    The ‘London Eye’ can be considered to be a circular frame of radius 67.5m on the
    circumference of which are ‘capsules’ carrying a number of people round the circle. Take
    a co-ordinate system where O is the base of the circle and Oy is a diameter. At any time
    after starting off round the frame, the capsule will be at height h metres when it has
    rotated .°θ

    Apparently answer is... 67.5(1-Cosθ)??? why?

    Thanks
