Abstract: Integral means of arbitrary order, with power weights and their companion means, where the integrals are taken over balls in $\mathbf{ R}^n$ centered at the origin, are introduced and related mixed-means inequalities are derived. These relations are then used in obtaining Hardy and Levin-Cochran-Lee inequalities and their companion results for $n$-dimensional balls. Finally, the best possible constants for these inequalities are obtained.
