input: Write a python function to return the area and perimeter of a circle.
  assert area_perimeter_circle(4) == (50.24, 25.12)
  assert area_perimeter_circle(0) == (0.0, 0.0)
  assert area_perimeter_circle(10) == (314.0, 62.8)
output: def area_perimeter_circle(radius):
      import math
      area = round(math.pi * radius * radius, 2)
      perimeter = round(2 * math.pi * radius, 2)
      return (area, perimeter)
