5 次の英文は,家族の夜の外食行動(eating out behavior)に関する調査について述べたもので ある。英文と表を良く読み, あとの問題に答えなさい。 なお, 計算等を行う場合は、この問題の ページの余白で行うこと。 Kakeru and his friend Judy go to a university in Japan. They decided to work together to do some research about people's eating out behavior at night. They sent several questions to 300 families with children in elementary or junior high school. They asked what day of the week the families eat out at night the most and what their primary reason for eating out is. The results are shown in the tables below. Table 1 shows the days of eating out at night. According to the results of the survey, Monday is the lowest percent of all. Only one percent of the families eat out on Monday. The percent of families who eat out on Thursday is half of the percent of Wednesday. On Sunday, ten percent of families eat out. The rate of families choosing Friday or Saturday night for eating out is more than 70 percent, and Friday is higher than Saturday. Why do more families choose Friday and not Saturday for eating out? Many adults and children are on a five-day week, and Saturdays and Sundays are their days off. So, they eat out on Friday night as a reward for finishing the week's work or school. In Table 2, we can see various reasons for eating out at night, but more than 60 percent of the answers are related only to parents. Parents usually make meals for the family, and other members sometimes help to cook. As a result, when parents cannot make dinner, the family eats out. The percent of "For a change" is about half of "All family members come home too late." The research also shows that most children want to eat out more often, but about 50 percent. of parents think they eat out too much. They worry about the cost of eating at restaurants.

Fineが終わり、Codaが結び、で習ったんですけど、違いってなんですか？意味が一緒にしか思えなくて……

x＝2sinθと置いて積分したのですがどうしても8π^2になってしまいます。 どこが間違ってるのか教えて欲しいです
