[some code cut]

In your circle_area() function:

###
def circle_area():
    print "would you like to input radius or diameter?"
    print "1. radius"
    print "2. diameter"
    question = input ("> ")
    if question == 1:
        print "what is the radius?"
        radius = input("> ")
        radius = 3.14*radius**2
        print radius
    elif question == 2:
        print "what is the diameter?"
        diameter = input ("> ")
        diameter = diameter/2
        diameter = diameter**2 * 3.14
        print diameter
###

in the second case, since you're dividing the diameter by 2, it's
perfectly ok to call that result the radius.

###
    # ...
    elif question == 2:
        print "what is the diameter?"
        diameter = input ("> ")
        radius = diameter/2
        area = radius**2 * 3.14
        print area
###

Likewise, we can call the thing that holds the area the variable name:  
"area".  You don't need to reuse "diameter" as a variable if it no longer
represents the diameter.  Electrons are still in abundant supply, despite
the power crisis here. *grin* In short: it's perfectly ok to be a little
indulgent with variable names if we're in a function.

Your code looks good.  Keep the questions coming!
