查询词典 radius of a circle

The "no-charge area," formerly a two-by-six foot box where an offensive foul is not called if contact is made with a secondary defensive player who has established a defensive position, will be expanded to the area consisting of a half circle with a four-foot radius measured from the middle of the goal.

翻译成中文就是这段：以篮筐为圆心，4英尺为半径的半圆区域之内，进攻球员撞击已确定防守位置的辅助防守球员将不被判进攻撞人犯规。这一区域过去是一个2x6英尺的矩形。所以我也一直有疑问到底no-charge area是上面时候出现的。还是上面这段文字的翻译我翻译错误了？
