On a class of Finsler metrics of scalar flag curvature defined by the Euclidean metric and related ‎‎۱‎‎-forms

‎‎In this paper, we study a class of Finsler metrics called general spherically symmetric Finsler metrics which are defined by the Euclidean metric and related ‎‎۱‎‎-forms. For a class of the metrics in ‎R‎n‎‎, we prove that it is projectively flat if and only if it is of scalar flag curvature.‎
