大本钟一伦敦市的标志。钟盘上时针的长度时2.75m。大本钟的时针经过6小时，时针的尖端走过的路程是多少米？经过9小时呢？

London is well-known because of Big Ben

伦敦市的标志性建筑----大本钟,巨大而华丽,它的分针长4.27m.大本钟的分针1小时扫过的面积是多少平方分米?（得数保留两位小数）
3.14×4.27×4.27×60=3435.07836平方米=343507.84平方分米
爷爷家养的一只小狗,把它拴在长7m的院墙跟喂养,（绳栓在院墙根的一半,院墙根就是一条直线）,栓狗的绳长2m,请你计算小狗最大的活动范围的面积是多少.
3.14×2²÷2=6.28平方米
一个花坛的直径是5m,在它的周围铺一条1m的环形鹅卵石小路.小路的面积是多少平方米?
3.14×3.5²-3.14×2.5²=38.465-19.625=18.84平方米
一辆汽车轮胎的外直径是80cm,如果平均每分钟转200圈,当他通过一座长1500m的大桥是,大约几分钟,（得数保留整这个题目有问题

12小时扫过的也就是一个圆的面积=3.14×2.8²=24.6176平方米≈24.6平方米
它的时针针尖12小时走过的路刚好是圆的周长=3.14×2.8×2=17.584米

"Big Ben" is located in the north of the river Thames to parliament,stand tall tower,with a big clock,called the great this ".Every hour,according to Greenwich time clock out the sound of heavy strains,in a few miles away can also hear the bell of the cemetery.
In 1859,the clock from the time of king works minister Benjamin Franklin hall jazz producer,the clock weigh 21 tons,casting cost 27000 pounds.
Big Ben is regarded as the symbol of London,who go to London for sightseeing,think of all around the clock tower,standing on the bridge in parliament to admire London this unique architecture.

时针一天24h转了两圈 那么四根时针总共扫过的面积应该是‘8πr²=8×3.14×3²=226.08㎡’

2x3.14x4.27x5=134.078 答：走过的路程约是134米。

一昼夜为24小时,大本钟的时针针尖刚好走2圈
根据圆的周长公式得
2×3.14×2.75×2=34.54（米）



答：大本钟的时针针尖一昼夜走过的路程是34.54米.

应该是半小时!

白金汉宫 【范文,仅供参考】　The graceless colossus of Buckingham Palace, popularly known as "Buck House", has served as the monarch's permanent London residence only since the accession of Victoria. Bought by George III in 1762, the building was overhauled by Nash in the late 1820s, and again by Aston Webb in time for George V's coronation in 1913, producing a palace that's about as bland as it's possible to be. 　　For two months of the year, the hallowed portals are grudgingly nudged open; timed tickets are sold from the tent-like box office in Green Park at the western end of The Mall. The interior, however, is a bit of an anticlimax: of the palace's 660 rooms you're permitted to see just 18, and there's little sign of life, as the Queen decamps to Scotland every summer. For the other ten months of the year there's little to do here, since the palace is closed to visitors – not that this deters the crowds who mill around the railings, and gather in some force to watch the Changing of the Guard, in which a detachment of the Queen's Foot Guards marches to appropriate martial music from St James's Palace (unless it rains, that is). 　　You can view a small selection of the Royal Collection – which is more than three times larger than the National Gallery's – at the Queen's Picture Gallery (daily 9.30am–4.30pm; ￡4), round the south side of the palace on Buckingham Palace Road. The exhibitions usually include some works by Reynolds, Gainsborough, Vermeer, Rubens, Rembrandt and Canaletto, which make up the bulk of the collection. 　　There's more pageantry on show at the Nash-built Royal Mews (April–Sept Tues–Thurs noon–4pm; Oct–Dec Wed only; ￡3.50), further along Buckingham Palace Road. The royal carriages, lined up under a glass canopy in the courtyard, are the main attraction, in particular the Gold Carriage, made for George III in 1762, smothered in 22-carat gilding and weighing four tons, its axles supporting four life-size figures.

Big Ben

lz,不好意思,我对大本钟不是很了解,所以帮你找了几篇,你看看吧：
（一）
Big Ben is the colloquial name of the Clock Tower of the Palace of Westminster in London and an informal name for the Great Bell of Westminster,part of the Great Clock of Westminster.The clock tower is located at the northwestern end of the building,the home of the Houses of Parliament,and contains the famous striking clock and bell.
（二）
People all over the world write to Big Ben.They even send birthday presents.One present was a bottle of oil,to help keep Big Ben running.Big Ben is not a person.It's a clock!
Big Ben is a great clock high up in a tower of the parliament (议会) building.This is the building in London where laws are made.The people of London like to see Big Ben's friendly faces.They like to hear the chimes (钟曲声) every 15 minutes.They like to hear the big bell striking on the hour.BONG!BONG!BONG!
Radio sends the sound of the big clock to the rest of the world.The BBC began to broadcast the chimes in 1924.Ever since,Big Ben has been a radio star.
Big Ben's story started in 1834.In that year the old Parliament building burned down.Its clock tower crashed to the ground.There had to be a new building-and a new clock.
Plans were made.They called for a "King of Clocks,the biggest and best in the world".So the clock had to be big.And it had to keep very good time.
The big clock was made in two years.Five more years went by before the clock tower was finished,then the four bells for the chimes were brought into the tower.And at last the giant (巨大的) hour bell was put in place.It rang out for the first time on July 11,1859.
This great bell had to have a name.A meeting of Parliament was called to pick one.The talk about names went on and on.Then Benjamin Hall got up to speak.He was a big man that the others liked.By this time they were all tired.Someone shouted,"Why not call it Big Ben?"
Everybody laughed,and the meeting broke up.The name Big Ben came from then on.
（三）
Big Ben is one of London's best-known landmarks,and looks most spectacular at night when the clock faces are illuminated.You even know when parliament is in session,because a light shines above the clock face.The name Big Ben actually refers not to the clock-tower itself,but to the thirteen ton bell hung within.The bell was named after the first commissioner of works,Sir Benjamin Hall.
我本人认为符合lz水平的是（一）
再推荐一篇本人的英语作品：
Hello,let me tell you about my best neighbor.My best neighbor's name is jingjing and she is a very lovely girl.She is only 7 years old now but she is very clever.One day,I went to play with her at her home.She let me look at her photos and told me the story of each photo.Suddenly,I looked at a picture and said,"Who is so ugly?"jing jing said nothing but cried.I realized that I should not say that,because the ‘ugly’ girl is she.But now we are best freinds!
This is my neighbor,a cute and beautiful girl.
译文：哈喽,让我来告诉你我最好的邻居（的故事）吧,我最好的邻居名字叫晶晶,她很可爱.她只有七岁但是她很聪明.有一天,我到她家去玩,她让我看了看她的照片,并且（她还）告诉我每个照片（背后的）故事.突然,我看见了一张照片,问她：“谁这么丑啊?”晶晶什么也没说,但她哭了.我意识到我不该这样说,因为那个“丑”女孩就是她呀.现在,我们（仍)是最好的朋友!
这就是我的邻居,一个可爱而漂亮的女孩.

作为伦敦市的标志以及英国的象征,大本钟巨大而华丽,重13.5吨,四个钟面的面积有两平方米左右.大本钟从1859年就为伦敦城报时,至今将近一个半世纪,尽管这期间大本钟曾两度裂开而重筹.现在大本钟的钟声仍然清晰、动听.
位于 Westminster Bridge的南面桥头,与 Houses of Parliament 相连,是伦敦的传统地标,坐地铁可以在 Westminster 站下车.

时针所走的路程就是以时针为半径的一个圆弧!经过6小时刚好是圆周长的一半,即（2π×2.75）÷2
经过9小时刚好是圆周长的3/4倍即 （2π×2.75）×3/4

大本钟从1859年就为伦敦城报时,根据格林尼治时间每隔一小时敲响一次.为庆祝伦敦奥运揭幕,伦敦著名地标大本钟在3分钟内连响40下.这是大本钟继1952年2月15日以来首次打破常规鸣钟计划,也是英国“大规模鸣钟”活动的一部分.

I would like to visit the Buckingham Palace ,the Big Ben,the Thames River,and Houses of Parliament in London .

园的周长是2πr 则为2.75×π×2=17.27 一天走2圈 一天走了34.54

第一个问题：2.75陈2陈3.14再除以2

6小时：2*3.14*2.75*（6/12)
9小时：2*3.14*2.75*（9/12)

London is famous for its Big Ben,Buckingham Palace nad Tower Bridge

体育场

将半径r=2.75带入周长公式得出周长C然后6小时是周长的一般9小时是周长的4分之3,具体的你最近算算了

so simple……我汗,楼主是小学生么- -

ig ben

一昼夜=24小时 钟表只有 1到12 ,所以走两圈.针尖 走的路径 就是 两个圆的周长长度.
又：圆周长公式 =2πr （r 即 时针长度）
所以总路径的等于=2*2πr=4πr=4*3.14*2.75=34.54(米)
答：大约走了 34.54米.

大本钟转动五周?
大本钟的时针转动五周
时针的尖端走过的路程;3.14×2.75×2×5=86.35米

以时针长为办半径，6小时为圆周长二分之一，9小时为圆周长三分之一

译The Big Ben is a museum

2.75×2×3.14=34.54m
