你必须告诉我正方形和圆形的周长是不是一样,如果正方形周长比较长的话,那爬圆形的快,反过来道理也一样.这和面积没关系,主要是周长问题.

爬圆行先完成,爬正方行的,蚂蚁遇到直角的时候多半会回头,所以这样就爬不了一圈...,,

这个不知道什么条件,鬼也不知道他们谁快

假设正方形的边长与圆的直径相等为a,内切圆,则正方形周长为4a,圆的周长为3.14a,所以圆先爬完
假设圆的直径与正方形对角线相等为a,外接圆,则正方形的周长为2a倍根号2,圆的周长为3.14a,所以正方形先爬完

两只蚂蚁同时出发,用同样的速度,分别沿着正方形和圆形爬圆,你认为谁先爬完?为什么正方形长5cm圆形直径是5cm 两只蚂蚁同时出发,用同样的速度,分别沿着正方形和圆形爬一圈,谁会先爬完?为什么?急急急急急急急急急急急急急急急急急急急急急急急急急急急jjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjj 两只蚂蚁的速度相同,它们分别从A点出发.一只蚂蚁沿着大圆跑,另一只蚂蚁沿着里面的两个小圆个?两只蚂蚁的速度相同,它们分别从A点出发.一只蚂蚁沿着大圆跑,另一只蚂蚁沿着里面的两个小 两只蚂蚁速度相同,它们他们同时从A出发.A蚂蚁沿着大圆跑一圈,B蚂蚁沿着里面的两个小圆跑一圈(不重复两只蚂蚁的速度相同,它们他们同时从A出发.一只蚂蚁沿着大圆跑一圈,另一只蚂蚁沿着 两只蚂蚁的速度相同,它们他们同时从A出发.一只蚂蚁沿着大圆跑一圈,另一只蚂蚁沿着里面的两个小圆跑一圈 两只蚂蚁速度相同,它们他们同时从A出发.A蚂蚁沿着大圆跑一圈,B蚂蚁沿着里面的两个小圆跑一圈(不重复要列式 两只小蚂蚁的速度相同,他们同时从A点出发.一只蚂蚁沿着大圆跑一圈 已知:如图,在矩形ABCD中,AB=10cm,BC=20cm,两只蚂蚁P和Q同时分别从A,B出发,沿着AB,BC向B,C方向前进,P蚂蚁每秒钟走1cm,Q蚂蚁的速度是P蚂蚁速度的2倍,结果同时到达点B和点C,两只蚂蚁的运动时间为t秒. 已知:如图,在矩形ABCD中,AB=10cm,BC=20cm,两只蚂蚁P和Q同时分别从A,B出发,沿着AB,BC向B,C方向前进,P蚂蚁每秒钟走1cm,Q蚂蚁的速度是P蚂蚁速度的2倍,结果同时到达点B和点C(4)如果P蚁,Q蚂蚁继续沿BC→CD 甲乙两只蚂蚁同时从A点出发,甲沿着外侧爬行,乙在里面两个小圆沿“8”字型爬行.如果两只蚂蚁爬行的速度相同.问:甲先到还是乙先到?为什么? 甲乙两只蚂蚁同时从A点出发,甲沿着外侧的大圆爬行,乙在里面两个小圆沿“8”字型爬行,如果两只蚂蚁爬行 一张圆形纸片,直径10厘米,沿直径对折再对折后,等到一个新的图形,计算这个新图形的周长.2.两只小蚂蚁的速度相同,它们同时从A点出发。一只蚂蚁沿着大圈跑一圈,另一只蚂蚁沿着里面的两 长方形ABCD中AB:BC=5:4.位于A点的第一只蚂蚁按A-B-C-D-A的方向,位于C点的第二只蚂蚁按C-B-A-D-C,的方向同时出发,分别沿着长方形的边爬行.如果两只蚂蚁第一次在B点相遇,则两只蚂蚁第二次相遇在 两只蚂蚁进行速度比赛.两只蚂蚁进行速度比赛.他们同时从A点出发,按箭头方向一相同的额速度分别在两个圆上爬行.已知两圆的直径是48和30厘米问当蚂蚁爬行几整圈时两只蚂蚁相距最远? 一个圆的周长是5.4米,两只蚂蚁从一条直径的两端同时出发沿着圆周相向爬行(看问题补充)爬行的速度分别为每秒爬3.5厘米和每秒爬5.5厘米,它们每秒爬行1秒、3秒、5秒...连续奇数就调 两只蚂蚁的速度相同,他们同时从a点出发.一只蚂蚁沿着里面的两个小圆各跑一圈(不走重复路线).哪只小蚂蚁先回到出发点?请简要说明理由.(大院直径等于两个小圆的和) 两只蜗牛同时从一个等腰三角形的顶点出发,分别沿着两腰爬行.一只蜗牛每分钟爬行2.5米,另一只蜗牛每分钟 两只蜗牛同时从一个等腰三角形的顶点出发,分别沿着两腰爬行.一只蜗牛每分钟爬行2.5米,另一只蜗牛每分钟
