A15.0 cm long cylindrical glass tube, sealed at one end, is filled with ethanol. the mass of ethanol needed to fill the tube is found to be 11.86 g. the density of ethanol is 0.789 g/ml. calculate the inner diameter of the tube in cm.

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743
