In order to find out the area of a circle in Python, you have to know the radius of the circle. The formula for determining the area of a circle isA=πr². In case you have the diameter of the circle, the formulaA=1/4πd2has to be used. There is another formula with circumfe...
Python Code:# Import the 'pi' constant from the 'math' module to calculate the area of a circle from math import pi # Prompt the user to input the radius of the circle r = float(input("Input the radius of the circle : ")) # Calculate the area of the circle using the formula: ...
"""Returns the area of a circle with the given radius. For example: >>>area(5.5) 95.033177771091246 """ return math.pi*(r**2) 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 上述代码中定义了一个计算圆面积的函数,函数名为area,半径r作为为参数。 *格式约定:python文档字符串通常用三引号标识文档...
有了函数,我们就不再每次写s = 3.14 * x * x,而是写成更有意义的函数调用 s = area_of_circle(x),而函数 area_of_circle 本身只需要写一次,就可以多次调用。 抽象是数学中非常常见的概念。举个例子: 计算数列的和,比如:1 + 2 + 3 + ... + 100,写起来十分不方便,于是数学家发明了求和符号∑,可...
请简述Python中的继承机制。设计一个Circle(圆)类,该类中包括属性radius(半径),还包括___()、get___area()(求面积)共方法。设计完成后,创建Circle类的对象求周长和面积的功能。相关知识点: 试题来源: 解析 init#perimeter()(求周长)和get 反馈 收藏 ...
Write a Python program that creates a function that determines if a given point (x, y) is within a specified circle area using boolean conditions.Sample Solution:Code:import math def check_point_in_circle(x, y, center_x, center_y, radius): distance = math.sqrt((x - center_x)**2 +...
getcircleArea函数求圆的面积python 定义函数getCircleArea(r),可以对指定r计算圆面积。计算公式math库的pi*r*r。 定义函数get_rList(n),功能:输入n个值放入列表并将列表return。 输入n,调用get_rList(n)获得列表rList。 遍历rList,对每个元素调用getCircleArea,并按格式输出。 注意:需导入程序中所需要的库,...
