    (4x / 2x) = 3/ 1

    New linear measurement = Old linear measurement * scale factor

    So then would the dimensions of the original cylinder be multiplied by the scale factor? I think?

    so we have 4 as an old linear measurement. so to find the new linear measurement NL = 4 * ( 3/1) , where NL is new linear measurement
