Answer 1

I don't know about python 2.7, but for python 3 you could do

pi = 3.141592
rad = float(input())
print("Area of circle is ", (pi*rad*rad) )

Also, a circle doesn't have volume. A sphere would have volume but it's surface area formula isn't the one in the code.
And I would recommend you not to do int(input()) but rather do float(input()) unless you want the radius to be explicitly an integer

Answer 2

For few chars less, you can spare the pi assignement:

rad = float(input())
print("Area of circle is ", 3.141592*rad*rad )

Answer 3

must use function overloading
