    Geometry Scotland area problem

    I cant seem to figure this one out

    The historic Scotland society is resorting parts of Tantallon castle in north Berwick it contains 3 main spiral staircases. they want to restore one staircase first to be sure their idea works before extending it to all 3 after restoring the staircase they are going to put a protective layer on top of each step to help preserve it against all the walking that is done on the stairs if there are 42 steps in the spiral staircase they are going to restore how much step protector will they need to buy to cover the tops of the steps

    im given a picture of a cone with one of the sides 98cm and the vertex angle of 24 degrees

    any ideas
    ?

    I believe some information is left out.
    Letīs try to examine given info:
    1) 3 staircases
    2) 42 steps (in each staircase?)
    3) Some "cone" with some (side??) of 98cm.
    4) Some angle of the cone?
    We need to know something more about how big each step is?
    By cone do you mean "circle sector" that is suppose to represent a step?

    Yea the cone represents a single step I believe i need to find the area of the single step I'm guessing. Then multiply it by 42.
