3 . 2022年北京冬奥会期间,小明对火炬(图22-1)产生了浓厚的兴趣,于是准备动手制作一个简易火炬(图22-2).通过思考,小明初步设计了一个平面图,如图22-3所示,其中
为直角梯形,且
,
,
,
,
,曲线
是以C为圆心的四分之一圆弧,
为直角三角形,
,将平面图形
以
所在直线为轴,旋转一周形成的几何体即为小明设计的简易火炬.
(1)求该简易火炬的体积;
(2)小明准备将矩形
(如图22-3所示,该矩形内接于图形
,M在弧
上,N在线段
上,
与
重合)旋转所形成的几何体都用来安放燃料,设
,
①请用
表示燃料的体积V;
②若火炬燃烧时间t和燃料体积V满足关系
,请计算这个简易火炬燃烧的最长时间.
