Wow, talk about a rough start. Maybe it's just me but this was not the first question I was expecting. Needless to say, I got it wrong. Please answer and explain.

Let r= radius

OP = r
OX =sqrt(2)r

PX = OX-OP

Thus, sqrt(2)*r - r = 1

You can now find r and then the circumference. I get 5*pi as the answer
