In the figure below, Q is a point on the circle whose centre is O and whose radius is r, and OPQR is a rectangle. What is the length of diagonal PE?

A $$r$$

B $$r ^2$$

C $$r ^2/pi$$

D $$r \sqrt{2}/pi$$

E Cannot be determined from given information

There is a typo in the stem, diagonal PR not PE.

OPQR is a rectangle with diagonals OQ and PR.
the length of diagonal OQ is equal to radius of circle i.e. r.
since the diagonals of rectangles are equal in length , thus
PR=OQ=r.

My reasoning for this is since OPQR is a rectangle, OQ=PR and because OQ is also a radius, it can also be referred to as r. Re: GRE Math Challenge #10- Q is a point on the circle whose   [#permalink] 23 Jun 2018, 00:21
