1 . 水车是古代中国劳动人民发明的灌溉工具,相传为汉灵帝时华岚造出雏形,经三国时孔明改造完善后在蜀国推广使用.作为中国农耕文化的重要组成部分,它体现了中华民族的创造力,为中国农业文明和水利史研究提供了见证.被誉为“水车之都”的兰州建起了一处水车博览园,再现了以前黄河两岸水车林立的壮观景象.如图为一架新制作的水车,其最高点距离水面为18米,最低点在水面下2米,该水车每

8 . 球面被平面所截得的一部分叫做球冠(如图).球冠是曲面,是球面的一部分.截得的圆叫做球冠的底,垂直于截面的直径被截得的一段叫做球冠的高.阿基米德曾在著作《论球与圆柱》中记录了一个被后人称作“Archimedes’Hat-BoxTheorem”的定理:球冠的表面积
(如上图,这里的表面积不含底面的圆的面积).某同学制作了一个工艺品,如下图所示.该工艺品可以看成是一个球被一个棱长为4的正方体的六个面所截后剩余的部分(球心与正方体的中心重合),即一个球去掉了6个球冠后剩下的部分.若其中一个截面圆的周长为
