Ответ:

17,75 м²

Объяснение:

Голубая часть круга = 1/3 часть всего круга.

Если АР = РQ = QB = 2 м, тогда диаметр круга = 2 + 2 + 2 = 8 м

Площадь круга = пR²

R = D : 2 = 8 : 2 = 4 м

п = 3,14

S = 3,14 * 4² = 3,14 * 16 = 50,24 м²

Тогда площадь голубой части круга:

50,24 : 3 ≈ 17,74666… ≈ 17,75 м²

Three generations under the same roof

I have a big family. We all live with our grandparents in a three-bedroom house. However, this is not so easy. Many conflicts occur within our family for the simple reason that three generations live under the same roof. Unfortunately, this situation is typical of Poland where many families have to live together because of the shortage of flats.

Both my parents work. My mother is a psychologist and she does not like housework very much. My father is an engineer and he spends most of his time at work. For many years my grandparents have cared for our family. Both my sisters got used to it a long time ago. Whenever they have problems, they go to our grandmother and they know that they can always count on her help.

My parents and grandparents quarrel very often. There are problems which cannot be solved easily. My mother, for example, does not want to obey the rules laid down by our grandmother. She has her own ideas about raising children or housekeeping. Unfortunately, our mother does not have too much time because she works a lot. My grandmother, on the other hand, is a very strong-minded and Bossy woman. She thinks that she has the right to decide about everything in her own house. My mother objects to it and they often argue about such things as sharing the kitchen, helping around the house or spending money.

Similar problems exist in many families. Young people would like to be treated as partners but at the same time they would like to rely on the elders for help and advice
