Answer 1

Do not print anything other than what was required by the task, in this case, the area of circle. Delete the lines printing a prompt for radius input, and the radius value.

Answer 2

Just remember one thing "when someone gives you task, then don't print your own things, just print that thing which is mentioned".

So just print final value.
