title: How to find the circumference of a circle with an inputted area
body: <p>I am trying to create a code that will ask the user for the area of a circle, and from that find the circumference of it.</p>
  
  <p>So far I have got this code:</p>
  
  <pre><code>area = input("Please choose an area for your circle: ")
  def circumference(area):
      import math
      circumference = (squareRoot(area)) / (math.pi)
  
  print("The circumference is: ", circumference)
  </code></pre>
  
  <p>When the chosen area is 60, it returns:</p>
  
  <pre><code>Please choose an area for your circle: 60
  The circumference is:  &lt;function circumference at 0x101478510&gt;
  </code></pre>
  
  <p>How can I improve my code so that it works and why it would work?</p>
