问题 解答题

把141.3升水倒入一个底面周长18.84分米的无盖铁皮圆柱体水桶中,正好能倒满,请你算算这个铁皮水桶用铁皮多少平方分米?

答案

底面半径是:18.84÷3.14÷2=3(分米),

底面积是:3.14×32=28.26(平方分米),

圆柱水桶的高是:141.3÷28.26=5(分米),

它的侧面积是:18.84×5=94.2(平方分米),

所以铁皮水桶的铁皮是:28.26+94.2=122.46(平方分米);

答:这个铁皮水桶用铁皮122.46平方分米.

     As young students, you have many dreams. These dreams can be very big, such as winning the Nobel

Prize; they can also be small, such as becoming one of the best students in your class.

     Once you find a dream, what do you do with it? Do you ever try to make your dream real?

     Andrew Matthews, an Australian writer, tells us that making your dreams real is life's biggest challenge.

You may think you're not very good at some school subjects, or that it's impossible for you to become a

writer. Those kinds of ideas stop you from realizing your dream.

     In fact, everyone can realize his dream. The first thing you must do is to remember what your dream is.

Don't let it leave your heart. Keep telling yourself what you want every day and then your dream will come

true faster. You should know that a big dream is, in fact, made up of many small dreams.

     You must also never give up your dream. There will be difficulties on the road to your dreams. But the

biggest difficulty comes from yourself. You need to decide what is the most important. Studying instead of

watching TV will help you to get better exam results, while saving five yuan instead of buying an ice cream

means you can buy a new book.

     As you get closer to your dream, it may change a little. This is good as you have the chance to learn

something more useful and find new hobbies.
