Multiple lines?

[Noobie12]

Hello, everyone. I'm fairly new to coding and in a bit of a jam. I'm trying to type out this example i saw online on IDLE and it reads something like this.

1 response = input("What is your radius? ")
2 r = float(response)
3 area = 3.14159 * r ** 2
4 print("The area is ", area)

But MY code stops at the 2nd line.

>>> response = input("What is your radius?")
What is your radius?

What am I doing wrong or how do i get my code to look something like the example? And how come I can't code offline? Any help is greatly appreciated.
