的是理解掌握等底等高的圆柱与圆锥体积之间的关系及应用.21.[分析]根据正反比例的意义进行解答:即成正比例的两个量中,相对应的两个数的比值是一定的;成反比例得两个量中,相对应的两个数的乘积是一定的.[解答]解:由分析可得:成正比例的两个量的比值一定.故答案为:比值.[点评]此题属于成正、反比例的量的意义,就看这两个量是对应的比值一定,还是对应的乘积一定.22.[分析]每截一次就增加2个圆柱的底面,截成3段需要截2次,那么就增加了2×2=4个底面,由此可求得圆柱的底面积,然后利用V=Sh即可解决问题.[解答]解:根据题意可得:平均截成3段后就增加了4个圆柱底面的面积,所以圆柱的底面积为:12÷4=3(平方分米)3平方分米=0.03平方米由V=Sh可得:0.03×2=0.06(立方米).答:这根木料的体积是0.06立方米.故答案为:0.06.[点评]抓住表面积增加部分是4个圆柱底面的面积是本题的关键.23.[分析]已读的页数和总页数的比是7:12,那么已读的页数就是总页数的,把总页数看成单位“1”,第一天读了全书的25%,第二天读的页数就是总页数的(﹣25%),它对应的数量是40页,由此用除法求出总页数.[解答]解:40÷(﹣25%)=40÷=120(页)答:这本书原来有120页.故答案为:120.[点评]本题的关键是找出单位“1”,并找出数量对应了单位“1”的几分之几,再用除法就可以求出单位“1”的量.24.[分析]等底等高的圆柱的体积是圆锥的体积的3倍,把圆锥的体积看作1份,则圆柱的体积就是3份,相差(3﹣1)=2(份),相差96立方分米占2份求圆柱体积即求3份,求圆锥体积即求1份.[解答]解:96÷(3﹣1)=96÷2=48(立方分米)48×3=144(立方分米)答:圆柱的体积是144dm3,圆锥的体积是48dm3.故答案为:144;48.[点评]此题考查了等底等高的圆柱与圆锥的体积倍数关系的灵活应用.三.计算题(共3小题)25.[分析](1)根据等式的性质,方程的两边同时减去0.8;(2)先计算6.2x﹣x=5.2x,根据等式的性质,方程的两边同时除以5.2;(3)根据等式的性质,方程的两边同时乘上x,把方程化为3.1x=5.58,然后方程的两边同时除以3.1;(4)根据等式的性质,方程的两边同时加上97,然后方程的两边同时除以4.[解答]解:(1)x+0.8=7.6x+0.8﹣0.8=7.6﹣0.8x=6.8(2)6.2x﹣x=41.65.2x=41.65.2x÷5.2=41.6÷5.2x=8(3)5.58÷x=3.15.58÷x×x=3.1×x3.1x=5.583.1x÷3.1=5.58÷3.1x=1.8(4)4x﹣97=34.24x﹣97+97=34.2+974x=131.24x÷4=131.2÷4x=32.8[点评]本题考查解方程,解题的关键是掌握等式的性质:方程两边同时加上或减去相同的数,等式仍然成立;方程两边同时乘(或除以)相同的数(0除外),等式仍然成立.26.[分析](1)、(2)根据乘法分配律进行简算;(3)按照从左向右的顺序进行计算;(4)先算小括号里面的减法,再算中括号里面的除法,最后算乘法;(5)先算小括号里面的除法,再算小括号里面的减法,最后算乘法;(6)先算除法,再根据减法的性质进行简算.[解答]解:(1)=×+×=×(+)=×=(2)=2.2×+1.8×=(2.2+1.8)×=4×=(3)==(4)=×[÷]=×=1(5)=(1﹣)×=×=(6)=﹣﹣=﹣(+)=﹣1=[点评]考查了运算定律与简便运算,四则混合运算.注意运算顺序和运算法则,灵活运用所学的运算定律进行简便计算.27.[分析](1)计算零件的表面积,由于上面小圆柱体与下面的大圆柱体的结合面不外露,因此上面的小圆柱体只计算侧面积,下面的大圆柱体计算它的表面积,然后合并起来即可.(2)计算零件的体积就是计算两个圆柱体的体积之和.因此列式解答.[解答]解:(1)表面积:3.14×4×4+3.14×8×4+3.14×(8÷2)2×2=50.24+100.48+3.14×16×2=150.72+100.48=251.2(平方厘米)(2)体积:3.14×(4÷2)2×4+3.14×(8÷2)2×4=3.14×4×4+3.14×16×4=50.24+200.96=251.2(立方厘米)答:它的表面积是251.2平方厘米,体积是251.2立方厘米.[点评]此题解答关键是理解上面的小圆柱体与下面的大圆柱体的结合面不外露,计算表面积小圆柱体只计算他的侧面积;直接关键表面积和体积公式解答.四.操作题(共1小题)28.[分析](1)根据旋转的特征,三角形ABC绕点C顺时针旋转90°,点C的位置不动,其余各部分均绕此点按相同方向旋转相同的度数即可画出旋转后的图形.(2)根据平移的特征,把圆心现右平移5格,以平移后的点为圆心,同原圆的半径为半径画圆即可.(3)这个长方形长、宽分别是3格,2格,根据图形放大与缩小的意义,按2:1放大后的长方形长是3格,宽是4格.[解答]解:(1)画出三角形绕C点顺时针旋转90°后的图形(图中红色部分).(2)画出圆向右平移5格后的图形(图中绿色部分).(3)画出长方形按2:1放大后的图形(图中蓝色部分).[点评]图形平移只是位置的变化,形状、大小不变;图形旋转后只是位置、方向的变化,形状、大小不变;图形放大或缩小后,只是大小变了,形状不变.五.应用题(共5小题)29.[分析]根据图形放大与缩小的意义,一个长4cm、宽3cm的长方形按4:1放大后,长、宽都扩大到原来的4倍,放大后的长方形的长、宽都分别是16cm、12cm;根据长方形的面积公式S=ab即可求出面积,列式解答即可.[解答]解:4×4=16(厘米)4×3=12(厘米)12×16=192(平方厘米)答:放大后的长方形的面积是192平方厘米.[点评]本题是考查图形的放大与缩小、长方形的面积的计算.注意,一个图形扩大或缩小的倍数是指对应边扩大或缩小的倍数.30.[分析]根据圆柱的表面积=侧面积+底面积×2,圆柱的体积=底面积×高,把数据分别代入公式解答.[解答]解:3.14×8×5+3.14×(8÷2)2×2=125.6+3.14×16×2=125.6+100.48=226.08(平方米);3.14×(8÷2)2×5=3.14×16×5=50.24×5=251.2(立方米);答:这个圆柱的表面积是226.08平方米,体积是251.2立方米.[点评]此题主要考查圆柱的表面积公式、体积公式的灵活运用,关键是熟记公式.31.[分析]把这份稿件的总量看成单位“1”,小明需要5小时,小明的工作效率就是,小华需要4小时,小华的工作效率就是,它们的和就是合作的工作效率;再用1除以合作的工作效率,即可求出两人合作打印,需要多少小时.[解答]解:1÷(+)=1÷=(小时)答:两人合作打印,需要小时.[点评]解决本题关键是理解把工作总量看成单位“1”,再根据工作量、工作效率和工作时间三者之间的关系求解.32.[分析]根据比例尺的意义可知:实际距离=图上距离÷比例尺,求出实际距离,然后再化成千米即可;再根据关系式:距离÷速度和=相遇时间,解决问题.[解答]解:10÷=80000000(厘米)80000000厘米=800千米800÷(55+45)=800÷100=8(小时)答:两车经过8小时后相遇.[点评]此题考查了比例尺以及速度、路程与时间之间的关系.33.[分析](1)由图可以看出,时间为10秒时,出水量为2升、时间为20秒时,出水量为4升、时间为30秒时,出水量为6升、时间为40秒时,出水量为8升……(2)由统计图(表)可以看出,10:2=5,(20﹣10):(4﹣2)=5、(30﹣20):(6﹣4)=5……时间与出水量的比值是一定的.根据两种相关联的量,一种量变化,另一种量也随着变化,如果这两种量中相对应的两个数的比值一定,这两种量就是成正比例的量.由此可知,这个水龙头打开的时间和出水量成正比例.(3)过30秒与40秒中间的点作时间轴的垂线与表示水量的线相交,过这个交点作出水量轴的垂线,垂足处的数值就是35秒的出水量;同样,过出水量轴上表示16升的点作出水量轴的垂线与表示出水量的线相交,过这个交点作时间轴的垂线,垂足处的值就是出水16升的时间.[解答]解:(1)看图填表:时间/秒10203040…出水量/升2468…(2)根据如图的图象,这个水龙头打开的时间和出水量成正比例.(3)如图根据图象判断,35秒能出水7升;出水16升要用80秒.故答案为:正,7,80.[点评]此题主要是考查辨析两种量成正、反比例.关键是看这两种相关联量中所对应的数的比值(商)一定还是积一定。
