def area(self, c):return c**2 * self.n / 4 / tan(pi/self.n)
def volume(self, c):return 0
class Triangle(Ngone): n = 3
class Square(Ngone): n = 4
class Pentagon(Ngone): n = 5
class Hexagon(Ngone): n = 6
class Circle:
def perimeter(self, r):return 2 * pi * r
def area(self, r):return r**2 * pi
def volume(self, r):return 0
class Cube:

def area(self, c):return c**2 * 6
def volume(self, c):return c**3
class Parameters:
