The Born cross section and dressed cross section of e(+)e(-) -> b (b) over bar and the total hadronic cross section in e(+)e(-) annihilation in the bottomonium energy region are calculated based on the R-b values measured by the BaBar and Belle experiments. The data are used to calculate the vacuum polarization factors in the bottomonium energy region, and to determine the resonant parameters of the vector bottomonium(-like) states Y(10750), Upsilon(5S), and Upsilon(6S).
