Question
Recall the geometry example from class. Create new modules for triangles, spheres, and cylinders and populate them with functions for calculating perimeter and area in the 2-D case (triangles) and volume and surface area in the 3-D cases (spheres and cylinders). Now modify the geometry.py file to work with these as options for the user. SUBMIT: - A modified geometry.py file that works with the new modules you have created. - triangle.py, sphere.py, and cylinder.py files which contain the methods specified above. Attached: original geometry.py and an example for sphere.py
# The circle module has functions that perform # calculations related to circles. import math pi=math.pi # The area function accepts a circle's radius as an # argument and returns the area of the circle. def area(radius): return math.pi * radius**2 # The circumference function accepts a circle's # radius and returns the circle's circumference. def circumference(radius): return 2 * math.pi * radius
