The square is inside the ball. Given the perimeter of the ball shape and the perimeter of the square, find the shadow area outside the square inside the ball.
When Qin Yu saw this question, all the nerve cells in his head immediately became knotted, and he was filled with worry!
Mathematics is her natural enemy.
It was like this in my previous life, and it will be like this in this life too!
This question looks very simple, she can definitely complete it!
Qin Yu clenched her fists and gritted her teeth to encourage herself!
Gu Jin, who was lying on the bed, saw Qin Yu sitting at the table and ignoring him, and he turned back angrily to read.
However, what he didn¡¯t expect was that when he looked up inadvertently, he saw a super interesting picture.
Qin Yu, who was beside the dim butter lamp, scratched her head and slowly pulled her hair. Her originally black and smooth hair was grabbed like a chicken coop by her. He couldn't see her face, but just her back, he could I can imagine her brows furrowed into knots.
Encountering a problem?
Gu Jin suddenly felt a sense of schadenfreude in his heart. He was so awesome when he was so angry! It's fierce and aggressive.
Look, it¡¯s not because of the question!
Gu Jin thought for a while, he could actually lend her more books!
The more he looked at her tangled and sad back, the happier Gu Jin became. When he turned around to read again, the corners of his mouth became more and more raised.
After flipping through more than 10 pages of the book, when he looked up again, the oil lamp on the table flickered on and off, almost burnt out. The worried woman who refused to ask for help lay on the table like a tired cat. .
Gu Jin couldn't help laughing, got up from the bed, walked to the table, glanced slightly, and suddenly laughed out loud. He thought she had encountered some difficulty, but he didn't expect that the question she couldn't do was so simple.
Given the circumference, you can calculate the diameter of the circle and get the area. Subtract the area of ??the square from the area of ??the circle and the result is out.
She was actually calculating for a long time uh she didn't know how to calculate the formula for the area of ??a circle
Gu Jin could see Qin Yu's problem within a few seconds.
Based on this foundation, even if the college entrance examination is resumed, it will still be difficult to pass it.
????????????????????????But the disparity in strength is a bit too much!
"The formula for the area of ??a circleis it? Squared? Why did I forget it?" In the quiet night, the woman's sad murmur sounded faintly, tangled and sad.
When Gu Jin lowered her head, she could clearly see the small pimple on her fair forehead. Her long eyelashes were like cattail fans, casting deep shadows under the dim light. The mask was large, but it still couldn't cover her delicate and thin face. face.
Gu Jin instantly felt an inexplicable sense of shame for having laughed at Qin Yu just now.
He wants to struggle out of the environment he doesn¡¯t want to stay in, and she wants to change her destiny through knowledge. Who has the right to laugh at her?
She is so thin, but she works so hard!
Gu Jin bent down and picked up Qin Yu from the stool. The person in his arms seemed to be lighter than when he picked her up from the cold pool in the valley some time ago in Sichuan South County.
Gu Jin frowned and gently placed Qin Yu on the bed.
During this period, I ate meat every day, but the more I ate, the thinner and lighter I became. Is it because the meat has become less nutritious?
Gu Jin gently stretched her long arm under Qin Yu's neck and gently hugged her into his arms. His other hand went around her waist and hugged her whole body.
The little woman in her arms has been restless and wants to struggle, but she never wakes up.
Gu Jin stretched out her index and middle fingers and slowly crossed Qin Yu's brow. Gradually, the knot on her brow slowly disappeared.
The woman's slightly frowned eyebrows gradually relaxed, and she seemed to feel the warmth. She put her hands on his chest, tightly grasped the skirt of his clothes, and rubbed in his arms with nostalgia, as if she regarded him as the greatest warmth in her life.
She is really petite and exquisite. When I hugged her like this, I realized how slender she was. It seemed that if I applied too much force, her waist would break.
A sudden feeling of pity filled her heart and lingered, and Gu Jin hugged her tighter.
He didn¡¯t seem to resist her staying by his side as much as he imagined.
¡¡
When Qin Yu woke up again, he found that his pillow was a little different. It was not as soft as before, but not as hard. This pillow was firm and seemed to be elastic
Opening her eyes and turning her eyes for a moment, when she saw Gu Jin¡¯s handsome face that made people and gods angry, she was so frightened that her whole body trembled!
what happened?
Why did she sleep with him?
Is she still resting on his arm?
She was clearly going to lay the floor last night??, why did you come to the bed?
She climbed up on her own?
Climbing to Gu Jin¡¯s side?
The more Qin Yu thought about it, the more uncomfortable she felt. Why was she so hopeless? She was obviously far away from him, but her body was so shameless, so close to this man!
She pinched her thigh hard, pinched her thigh, and then pinched her face hard!
If Gu Jin wakes up and sees her sleeping next to him, he won't know how to mock her.
But with his sarcasm, she became even more angry with herself, angry that even when she fell asleep, she only wanted to be next to him.
How short of a memory she has!
The rebirth of this life will all be in vain!
Qin Yu quickly got up from the bed, stood in the room for a few seconds, and quickly made a mat on the ground.
After sitting on the floor for a few seconds, she felt even more inappropriate. If the guests found out, Gu Jin would think she did it on purpose.
After clearing the floor and putting the quilt in the cabinet, Qin Yu entered the kitchen.
¡¡
"Sister, we have to leave!" Qin Yu had just made the buns in the kitchen when he heard the sound of Heigouzi yawning and not waking up.
It was not yet dark outside, Black Gouzi was standing at the door of the kitchen, and Li Zhiming was already standing at the door of the yard, and they were preparing to leave early.
"If you want to leave, you have to have breakfast first! Look, sister has already made the buns, and there is glutinous rice in the pot. You can take them with you to eat on the way!" Qin Yu took the hot buns out of the steamer with long chopsticks and used The bowl is for the black dog.
Black Gouzi turned to look at Li Zhiming. Although Li Zhiming had a straight face, he did not object.
Black Gouzi happily handed the bun to Li Zhiming. Li Zhiming was not polite and ate it with big mouthfuls.
Hei Gouzi always told him before that he ate how much noodles Qin Yu made, but he didn't really believe it. Yesterday he had one meal at lunch and one in the evening, plus these steamed buns, and he completely believed it.
tasty!
Very delicious!
He really didn¡¯t expect that this girl who had been fooling him was so good at cooking!
Being able to eat such delicious food, he was not even angry after being fooled.
Chewing the soft and fragrant meat buns with rich meat filling and soup in his mouth, Li Zhiming frowned. It would be a pity for such a good girl not to be his grandson-in-law!
¡°Gouzi, be careful on the road, take good care of yourself and take good care of grandpa!¡± Qin Yu warned while they were eating the buns, wrapping a pot of buns in lotus leaves and putting them all into a bag. (Remember the website address: www.hlnovel.com
