Next time, please mention what kind of error you're getting.
Was it an indentation error? Because, as you pasted it, your code would lead to
one.
If I fix the indentation, as in
import math
def area(radius):
return math.pi * radius**2
def circumference(radius):
return 2 * math.pi * radius
it works fine for me.
HTH,
Stefan
