二、填空题1. 圆的周长公式是 ________。
2. 根据题目所给的半径为3的圆，其周长为 ________。
答案：1. C = 2πr2. 18π 或 56.52（保留两位小数）解析：圆的周长公式是C = 2πr，其中 C 代表周长，r 代表半径。
将半径 r = 3 代入公式，得到周长C = 2π × 3 = 6π，约等于18π 或 56.52。
三、简答题1. 请简述牛顿第三定律的内容。
答案：牛顿第三定律，也称为作用与反作用定律，表述为：对于任何两个相互作用的物体，它们之间的作用力和反作用力总是大小相等、方向相反。
解析：牛顿第三定律是描述力的相互作用的基本定律，强调了力的双向性，即一个物体对另一个物体施加力的同时，也受到另一个物体的反作用力。
四、计算题1. 已知一个直角三角形的两条直角边长分别为3cm和4cm，求斜边的长度。
答案：斜边长度为 5cm。
解析：根据勾股定理，直角三角形的斜边长度可以通过两条直角边的长度计算得出，即c = √(a² + b²)，其中 a 和 b 分别是两条直角边的长度。
将 a = 3cm 和 b = 4cm 代入公式，得到c = √(3² + 4²) = √(9 + 16) = √25 = 5cm。
