    Answer:

    r=70.01 cm

    Step-by-step explanation:

    Length of the sheet : l

    Height of the sheet : h

    Thickness of the sheet : t

    Radius of the solid cylinder : r

    Volume of the sheet : V=lth

    Volume of the solid cylinder is the same : V=(pi)(r^2)h

    lth=(pi)(r^2)h

    r=sqrt (lt/(pi))

    Putting in the numerical values and paying attention to the units of the lengths the answer is

    r=70.01 cm
