一個長方形的長是8cm，寬是5cm，分別以它的長和寬為軸旋轉，形成兩個圓柱.比較兩個圓柱的體積，哪個大？

繞長
體積=3.14×5²；×8=628立方釐米
繞寬
體積=3.14×8²；×5=1004.8立方釐米
所以
繞寬旋轉的體積大.

鐘錶上的分針旋轉的圈數與天數成什麼比例？
分母一定分子和分數值成什麼比例？
出粉率一定麵粉重量與小麥重量成什麼比例？
三角形的面積一定底和高成什麼比例？

1.正比因為一小時紛爭旋轉1圈，一天分針旋轉24圈
2.正比分子=分母×分數值
3.正比麵粉重量=小麥重量×出粉率
4.反比底=2×三角形的面積/高

已知：梯形ABCD中，AD‖BC，M、N分別是BD、AC的中點（如圖）.求證：（1）MN‖BC；（2）MN=12（BC-AD）.

（1）證明：連接AM並延長，交BC於點E（如圖2），∵AD‖BC，∴∠DAM=∠BEM，∠ADM=∠EBM，∵DM=BM，∴△ADM≌△EBM（AAS），∴AM=ME，AD=BE，∵M、N分別是AE、AC的中點，∴MN是△AEC的中位線，∴MN＝12EC，MN‖BC.（2）證明：∵EC=BC-BE=BC-AD，∴MN＝12（BC−AD）.
