6.此棱锥的高为2,设外接球半径为R,则(2-R)2+(26×32×23)2=R2,∴R=3,∴外接球的表面积是36π.答案:C2.(2010·辽宁大连2月)(基础题,易)如图,正四面体ABCD 的棱长为a ,点E 、F 分别是棱BD 、BC 的中点,则平面AEF 截该正四面体的内切球所得截面的面积为( )A .πa 224B .πa 288C .πa 248D .πa

侧+S 底=12·3a·12a +34a 2=3+34a 2.答案:A4.(基础题,易)棱长为a 的正方体中,连结相邻面的中心,以这些线段为棱的八面体的体积为( )A .13a 3B .14a 3C .16a 3D .112a 3解析:正八面体可以看做两个正棱锥拼接而成,其中正四棱锥的棱长为22a ,高为12a.则V =2·13·(22a)2·12a =16a 3. 答案:C5.(山东高考题)(能力题,中)如图,在等腰梯形ABCD 中,AB =2DC =2BC =2,∠DAB =60°,E 为AB 的中点,将△ADE 与△BEC 分别沿ED 、EC 向上折起,使A 、B 重合于点P ,则三棱锥P —DCE 的外接球的体积为( )A .43π27B .6π2C .6π8D .6π24解析:由已知条件知,平面图形中AE =EB =BC =CD =DA =DE =EC =1,∴折叠后得到一个正四面体.方法1:作AF ⊥面DEC ,垂足为F ,F 即为△DEC 的中心. 取EC 中点G ,连接DG 、AG , 过球心O 作OH ⊥面AEC , 则垂足H 为△AEC 中心.∴外接球半径可利用△OHA ∽△AFG 求得. ∵AG =32,AF =1-(33)2=63,AH =33.∴OA =AG·AH AF =32·3363=64.∴外接球的体积为43π×OA 3=43·π·6643=68π.故选C .方法2:如图,把正四面体放在正方体中, 显然,正四面体的外接球就是正方体的外接球.∵正方体棱长为22,∴外接球直径2R =3·22, ∴R =64,∴体积为43π·(64)3=68π. 故选C . 答案:C评析:与球有关的组合题是近几年高考中常考的题目,既可以考查空间想象能力及截面图的应用,又能考查学生的计算能力,在复习时,要注意总结一下常见的与球相切或与球内接形成的组合体中有关元素的求解.6.(能力题,中)如图中多面体是经过正四棱柱底面顶点B作截面A1BC1D1而截得的,已知AA1=CC1,截面A1BC1D1与底面ABCD 成45°的二面角,AB=1,则这个多面体的体积为()A.22B.33C.24D. 2解析:以正方形ABCD为底面,DD1为棱将上图补成一个正四棱柱ABCD—A2B1C2D1,如下图所示,∵截面A1BC1D1与底面ABCD成45°的二面角.∴原多面体的体积恰好为补成的正四棱柱体积的一半.∵AA1=CC1,易知∠D1BD为截面与底面ABCD所成的二面角的平面角.∴∠D1BD=45°.∵AB=1,∴BD=2,DD1= 2.∴正四棱柱ABCD—A2B1C2D1的体积V=1×2=

1和底面相邻两边AB 、AC 都成45°角,求这个三棱柱的侧面积.解:∵AA 1和底面AB 、AC 成等角,且为45°角,∴A 1在底面ABC 上的射影在∠BAC 的平分线AG 上,又△ABC 为正三角形,∴AG ⊥BC.∵A 1A 在底面ABC 上的射影在AG 上,∴BC ⊥A 1A.又A 1A ∥B 1B ,∴B 1B ⊥BC ,即侧面B 1BCC 1为矩形.∴S 11B BCC =B

∥平面BFD ,∴AE ∥FG ,而AE ⊥平面BCE ,∴FG ⊥平面BCE ,∴FG ⊥平面BCF ,∵G 是AC 中点,F 是CE中点,∴FG ∥AE 且FG =12AE =1,∵BF ⊥平面ACE ,∴BF ⊥CE ,∴Rt △BCE 中,BF =CF =12CE =2,∴S △CFB =12·2·2=1,∴V C —BFG=V G —BCF =13·S △CFB ·FG =13. 22.(经典题,中)(14分)如图,四棱锥P —ABCD的底面是正方形,PA ⊥底面ABCD.PA =AD =2,点M 、N 分别在棱PD 、PC 上,且PC ⊥平面AMN.(1)求AM 与PD 所成的角;(2)求二面角P —AM —N 的大小.(3)求直线CD 与平面AMN 所成角的大小.分析:(1)求∠AMD 或证线面垂直;(2)利用(1)的结论找角并求角;(3)延长CD 、NM 确定斜足,依题设可作角.解:(1)∵ABCD 是正方形,∴CD ⊥AD.∵PA ⊥底面ABCD ,∴PA ⊥CD.∴CD ⊥平面PAD.∵AM ⊂平面PAD ,∴CD ⊥AM.∵PC ⊥平面AMN ,∴PC ⊥AM.∴AM ⊥平面PCD ,∴AM ⊥PD.∴AM 与PD 所成的角为90°.(2)∵AM ⊥平面PCD(已证),∴AM ⊥PM ,AM ⊥NM.∴∠PMN 为二面角P —AM —N 的平面角.∵PN ⊥平面AMN ,∴PN ⊥NM.在Rt △PDC 中,CD =2,PD =22,∴PC =2 3.∵PA =AD ,AM ⊥PD ,∴M 为PD 的中点,PM =12PD = 2.∵Rt △PMN ∽Rt △PCD ,∴MN =CD·PM PC ,∴cos ∠PMN =MN PM =CD PC =223=33.∴∠PMN =arccos 33.即二面角P —AM —N 的大小为arccos 33.(3)如图,延长NM ,CD 交于点E.∵PC ⊥平面AMN ,∴NE 为CE 在平面AMN 内的射影.∴∠CEN为CD(即CE)与平面AMN 所成的角.∵CD ⊥PD ,EN ⊥PN ,∴∠CEN =∠MPN.在Rt △PNM 中,sin ∠MPN =MN PM =33.∴∠MNP ∈(0,π2),∵∠MPN =arcsin 33.∴CD 与平面AMN 所成角的大小为arcsin 33.误区警示:空间角转化为平面角时,要注意等值转化.如将异面直线所成角转移到三角形中后,其结果只能是锐角或直角,切忌出现钝角.反之,将二面角转化为平面角时,要根据图形特点先确定所求二面角的范围,再通过解三角形进行等值转化.评析:(1)①中若直接解△AMD,确定∠AMD的大小有困难,故考虑证AM⊥平面PCD,从而AM⊥PD,得所求角为90°.②找角的方法为“垂线法”.特别注意在表达过程中,明确何角为所求的一步不可少.③中确定斜线与斜线在平面AMN内的射影非常关键.(2)求角的过程即“一作、二证、三计算”的过程,考查作图、推理与计算能力,为近几年高考的热点.。
