    5.66 or 5

    Step-by-step explanation:

    area of a cylinder is pie r squared times height

    radius = half diameter

    radius = 2.5

    2.5 squared times 9 is 56.25

    56.25 time pie is about 176.625

    1000/176.625=5.66

    round down to 5 if a whole number is needed

    5 plates

    Step-by-step explanation:

    So to answer this question you have to find the volume of the pancakes. The equation for the volume of a cylinder is V=πr²h (V=volume r=radius h=height) then you just have to fill in the variables so you would enter π (2.5²) 9 to get your answer. You would divide the diameter in half to get the radius.
