A company is calibrating some measuring instrumentation and has measured the radius and height of one cylinder 8 separate times; they are in vector variables r and h. Find the volume from each trial, which is given by pi r^2h. Also use logical indexing first to make sure that all measurements were valid (> 0). >> r = (5.499 5.498 5.5 5.5 5.52 5.51 5.5 5.48]; >> h = [11.1 11.12 11.09 11.11 11.11 11.1 11.08 11.11]
