Your program should work fine, and it does, here. However, if you are using
IDLE, the problem is a known bug in IDLE ;) You have to type the number and
press enter in a different window than the one that shows the 'Enter is the
radius:' text. I dont have the exact text of the bug at hand, sorry, but if
you fiddle around, you'll find the right window.

It's fixed in newer versions of IDLE, by the way, as well as a number of
other things. If you use IDLE a lot, you might want to grab the newer
version: http://www.python.org/idle
