im trying to find the volume of a shape but the definition is not working : <p>i want the code to ask for the radius and length then the program will calculate pi<em>radius</em>radius*length from the definition area the print out the radius for example if at asks me the radius i put 5 same with the length it should say the volume is 392.75 </p>

<pre><code>def calculate_volume(radius, length):
    pi=3.142
    vol=pi*radius*radius*length



#main program
radius = int(input("enter radius: "))
length = int(input("enter length: "))
volume = calculate_volume(radius, length)
print("the volume: ",volume)
</code></pre>
