input: Write a python function to calculate the total area of a circle and a square given their radius and side length.
  assert calculate_total_area(4, 5) == 78.53981633974483
  assert calculate_total_area(3, 7) == 82.27433388230814
  assert calculate_total_area(0, 0) == 0
output: import math
  
  def calculate_total_area(radius, side_length):
      circle_area = math.pi * radius ** 2
      square_area = side_length ** 2
      return circle_area + square_area
