Non-selected assignments in the true love of mathematics series | Internships

Seeing that the next week's study is coming, I bravely passed the topic that I had thought about with my internship partner for an afternoon to the tutoring team leader of my study.
Sure enough, not qualified 🙈🙈🙈
Say yes, you can write questions that can be written with multiple answers.

Then I turned into an ostrich for the entire holiday, burying my head in the sand and not wanting to deal with it. In addition, I don't have any extra thoughts to write other articles. In fact, last Friday was very exciting, but I was an ostrich...
Today I finally couldn't take it anymore, so I went straight to ask my master teacher, and immediately changed the title to the following one. The picture below looks very simple~~ However, I am so handicapped that I can only draw stick figures. (Yes~~ Don't open your eyes so big, such a simple arrow and graph paper... 🤣🤣🤣

After the teacher has finished teaching the zoomed-in and zoomed-in scale diagrams, he gives an assignment of zoomed-in scale diagrams (Figure 1). Students are asked to draw a double-scaled diagram on the graph paper. The next day, Xiaoyu handed in his homework (picture 2).
Excuse me: Is Xiaoyu's homework correct? Please explain why it is correct or not.

The school's circular square with a diameter of 2 meters needs to be repainted. In the quotation provided by the young apprentice, it is estimated that 2 buckets of paint are needed to coat a circular square. The teacher and the father told the apprentice to go back and recalculate. Why? Please explain why.
(1 bucket of paint can wipe about 10 square meters)
