title: Python Sypherical volume
body: <p>"Given sphere_radius and pi, compute the volume of a sphere and assign to sphere_volume. Volume of sphere = (4.0 / 3.0) π r3 </p>
  
  <p>Sample output for the given program: 4.18878666667"</p>
  
  <p>I am to get the test to pass both when the radius of 1 is calculated and the radius of 5.5.  I can get one or the other to work but not both simultaneously.  Please assist me in correcting the code so that it will successfully pass the test to calculate sphere_volumes using the two different radius', 1 and 5.5 when I command it to print(sphere_volume)....  </p>
  
  <p>This is what I have and isn't working at all when I combine the two radius calculations in the code:</p>
  
  <pre><code>pi = 3.14159
  sphere_radius = 1.0
  sphere_volume = 0.0
  sphere_volume=(((4.0/3.0) * 3.14159) * 1**3)
  sphere_radius = 5.5
  sphere_volume=(((4.0/3.0) * 3.14159) * 5.5**3)
  
  print(sphere_volume)
  </code></pre>
