The tenth question of the blank filling question is what is the side length and area of a square with a circumference of 36? If there is no first question, this question is even a slightly difficult one. That is to say, when there is no second question, a small number of children will directly use the perimeter to multiply the perimeter to find the area. In fact, this kind of problem is nothing more than careless examination. Common questions in the examination: ① know the bottom area and height of the cylinder, find the side area, surface area, volume and bottom perimeter of the cylinder ② know the bottom perimeter and height of the cylinder, find the side area, surface area, volume and bottom area of the cylinder ③ know the bottom perimeter and volume of the cylinder, find the side area, surface area, height and bottom area of the circular column ④ know the bottom area and height of the cylinder, find the side area and surface area of the cylinder, Volume ⑤ given the side area and height of the cylinder, find the bottom radius, surface area, volume and bottom area of the cylinder [warm tip] judge the conditions for forming a triangle: given the length of three line segments, as long as the sum of the shorter two line segments is greater than the length of the third line segment, it can be judged that it can form a triangle; When the given ranges of the two sides and the third side are known to calculate the perimeter of a triangle, we must first judge whether it can form a triangle by using the trilateral relationship, and then calculate it First, the relationship among the three sides of a triangle.
