input: Write a function that computes the area of a circle given its radius. The function should return the computed area rounded to two decimal places.
  
  import math
  
  def area_circle(radius):
      return round(math.pi * (radius ** 2), 2)
  
  assert area_circle(5) == 78.54
  assert area_circle(10) == 314.16
  assert area_circle(0) == 0.0
  assert area_circle(7.5) == 176.71
  assert area_circle(2.3) == 16.62
output: import math
  
  def area_circle(radius):
      return round(math.pi * (radius ** 2), 2)
