python求圆柱体积和表面积

Question

想问一下这里怎么通过构造方法来求解如图这样的圆柱体体积和表面积呢

Answer 1

import math
class Cylinder:
    def __init__(self,radius,height):
        self.radius=radius
        self.height=height
    
    def area(self):
        return 3.14*self.radius**2

    def volume(self):
        return self.area()*height

c=Cylinder(4,6)
print(c.area())
print(c.volume())
