Ví dụ : chu vi hình tròn lớn là 6.28m
chu vi hình tròn bé là 3.14m
Vậy bán kính chu vi hình tròn lớn là 1 m
bán kính hình tròn bé là 0,5m
=> Diện tích hình tròn lớn = 3,14m2
Diện tích hình tròn bé = 0.785m2
Mà 3,14 : 0,785 = 4 lần
Đáp án : 4 lần

As we know, Each year Vietnam has more than 71,300 deaths due to environmental pollution, and garbage is one of the most main ingredients that lead to the pollution environment. So where does the cause start?. Not far from where we live, we can see a lot. The first reason is due to our perception, they do not have much knowledge about the harmful effects of garbage so they often throw waste indiscriminately. the second reason is due to factories, hospitals do not have proper waste treatment systems. The last reason is due to outdated waste treatment technology equipment. That are the main reasons that lead to the environmental pollution from garbage. So what do we need to do? In my oppinion, I think we should to improve the awaraness of people about harmful effects of garbage and introduce reasonable penalties on people who lack awaraness and we should use the things can reuse to reduce the amount of waste that is thrown out. Always strictly check the waste treatment system of factories and hopitals. We should upgrade to more modern waste treatment equipment to be able to handle waste in the best way.
