Hi, maraticus! How is your preparation? Do you have progress in Verbal?

Hi, bmwhype2! Really thank you for your posts in Verbal part, they are vary helpful!

hi walker, I haven't really started studying yet. I just got a GMAT book and I'm hoping to start studying some time next week. I'm a little intimidated by verbal section.

When I tried OG diagnostic test after 2 month preparation I was shocked with 23% in SC! Therefore, I decided to put Quant to the back burner I would like to recommend you to try Verbal as soon as possible and to concentrate on weaknesses. It is more efficient to do so than to perfect your excellent math skills (I unfortunately know that on my own experience )

i still dont get it. The area of a circle is give by pi*r^2.

in order to get the max area possible for the circle, dont we consider the max radius it can have ? And in this case, we can have a radius of 4 or 5. i chose the radius of 5 and got max area to be 25*pi.

the max radisu is not 5. u are confusing a inscribed circle with an inscribed oval.

the circle is inside the rectangle. it touches the rectangle at 2 points. the max radius possible is 4.

is there a definition of inscribed circle that im missing somewhere ? i thought an inscribe circle inside a polygon meant that the circle is tangential to each side of the polygon

technically an inscribed figure touches all sides of the larger figure.

i think the question itself is VERY faulty in its wording... the circle could touch the rect in 2 or 3 points.
