On a large piece of paper, Dana creates a “rectangular spiral”
by drawing line segments of lengths, in cm, of
1, 1, 2, 2, 3, 3, 4, 4, ... as shown. Dana’s pen runs out of ink
after the total of all the lengths he has drawn is 3000 cm.
What is the length of the longest line segment that Dana
draws?<spanclass=′latex−bold′>(A)</span> 38<spanclass=′latex−bold′>(B)</span> 39<spanclass=′latex−bold′>(C)</span> 54<spanclass=′latex−bold′>(D)</span> 55<spanclass=′latex−bold′>(E)</span> 30 Gauss
