The Ferris Wheel In 1893, George Ferris engineered the Ferris wheel. It was 250 feet in diameter. If a Ferris wheel makes 1 revolution every 40 seconds, then the function TT h(t) = 125 sin 0.157t + 125 - - represents the height h, in feet, of a seat on the wheel as a function of time t, where t is measured in seconds. The ride begins when t= 0.
