Has anyone come across this interview question?

Pretty much what I was thinking too!esvcg said:

A bit full on for role - but looks copied from a GCSE paper... 2min question though. Probably a basic test of "can this applicant see though the crap and see the basic maths"?
Not so sure that it's copied from a GCSE paper if this link is anything to go by:http://math.stackexchange.com/questions/35898/calc...
..or maybe they too over complicated it!!
Pi X r squared. I would just subtract the area of the small circle from the large one. But you need r. The rest is easy. But I can´t figure out if there is some over complicated way they want you to do it.
Anyway, to answer your question, I haven´t come across that in an interview. Not the type of question they ask me when being interviewed for a yachting job

Indeed, but r is not a quick calculation in this case.Anyway, to answer your question, I haven´t come across that in an interview. Not the type of question they ask me when being interviewed for a yachting job

imagine the smaller circle was in the middle of the bigger one, the answer is pi x 4.5 squared

Then I´d pick the phone up, and ask the client what the dia. of the circle is 
You're the only person I would employ. In the real world you want someone who is happy to put their hand up and ask for the relevant information. If a customer raised a large order with such cryptic information, the first thing to do is get them to clarify exactly what they want.When we are recruiting, we design our tests so the people need to ask for help. We make it very clear that help is available by phoning me and that we are testing how they would actually work in the office. I've never employed anyone who doesn't ask questions about the test.

You don't need to know the diameter of either circle, you just need to know what the difference is - it's 9cm.
So the difference in the radius of each circle is 4.5cm.
From that you can work out the area of the moon.

Go on then, and show your working, without copying from the weblinks...So the difference in the radius of each circle is 4.5cm.
