Hi, I need to find the area of a circle for math class. Can you help me do that?
user
Sure, it sounds like you’re looking for the circumference. How large is the circle?
assistant
Not the circumference, the area. All I know about the circle is the radius, which is 5.
user
Alright, that should be easy.  So the area of the circle would be π*r2, right? So I guess you want to know how many square units are in the radius, then just multiply it by two?
assistant
So you're saying it's pi, times radius squared? So in this case, that would be pi times 25, or approximately 78.54?
user
Yep, I was right!  Isn't this pretty easy? You did this math homework, right?

Oh no, that’s wrong. You want to multiply pi, and 5, which is (3.141592653589793)*5, or approx. 22.85.  So
