A two-layer model of a satellite interior with a rocky core with a density 3 - 3.4 g cm-3 and with a H2O mantle with a density 0.94 - 1.2 g cm-3 is applied for the icy satellites. The case of Mimas is discussed separately. A comparison of the results with these obtained for more complicated models as applied for Jupiter and Saturn icy satellites has been carried out. This comparison shows that the two-layer model offers a reasonable approximation and, therefore, it can be applied for the satellites of Uranus. The author obtained the dimensionless core radii 0.55 - 0.74, 0.45 - 0.68, 0.59 - 0.67, 0.55 - 0.65, and dimensionless core masses 0.42 - 0.72, 0.26 - 0.63, 0.47 - 0.61, 0.41 - 0.57, for Ariel, Umbriel, Titania, and Oberon, respectively.
