57. The Ferris Wheel In 1893, George Ferris engineered the Ferris Wheei. It was 250 feet in diameter. If the wheel makes 1 revolution every 40 seconds, then S uin(a.157-)+ 25 h(1) - 125 sin0.157 - + 125 represents the height h, in feet, of a seat on the wheel as a function of time 1, where t is measured in seconds. The ride begins when 0.
