1.已知函数g（x）=a﹣x2（ {#mathml#}{#/mathml#} ≤x≤e，e为自然对数的底数）与h（x）=2lnx的图象上存在关于x轴对称的点，则实数a的取值范围是{#blank#}1{#/blank#}．
2.公元263年左右，我国数学家刘徽发现，当圆内接多边形的边数无限增加时，多边形面积可无限逼近圆的面积，由此创立了割圆术，利用割圆术刘徽得到了圆周率精确到小数点后面两位的近似值3.14，这就是著名的徽率．如图是利用刘徽的割圆术设计的程序框图，则输出的n值为（ ）
参考数据： {#mathml#}{#/mathml#} ，sin15°≈0.2588，sin7.5°≈0.1305．
