Author:Ivars Peterson (Math Muse for Kids)
Description: Have you ever wondered why the cover of a manhole is nearly always round? Why couldn't it be oval or square? The usual answer is that a circular lid, unlike a square or an oval cover, won't fall through the opening, but the circle isn't the only shape that would work safely as a manhole cover. Another possibility is the Reuleaux triangle... [Produced 10 times a year by the publishers of Cricket magazine (in association with Smithsonian magazine), Muse features articles and activities for children 8 years old and up.]
