Talk:Mock AIME 2 2006-2007 Problems/Problem 7

Either the image or the problem is wrong -- the slant height is given as 34 centimeters but is labelled 51 in the diagram. Which one is it? --JBL 21:09, 15 September 2006 (EDT)

I believe the image (51 cm) is correct, as it implies the given answer.

Shaded circle?

How do we know that the shaded region is a circle? --1=2 15:59, 27 March 2012 (EDT)
