At t = 0 seconds, the ferris wheel starting turning and the height of the rider above the ground in feet is given by h(t)=70?50cos(?t45)h(t)=70-50cos(?t45). a) What is the radius of the ferris wheel? feet b) How long does the ferris wheel take to make one revolution? seconds c) When does the rider first reach a height of 33 feet? Give your answer to the nearest second. at about seconds
