1. Two gears of radii 2.5 cm and 4.8 cm are adjusted so that the smaller gear drives 0O arger one, as shown. If the smaller gear rotates counterclockwise through 225', through how many degrees will the larger gear rotate? 2.5 cm 4.8 cm 2. A frequent problem in surveying city lots and rural lands adjacent to curves of highways and railways is that of finding the area when one or more of the boundary lines is the arc of a circle. Approximate the total area of the lot shown in the figure. 40 m 60° 30 m
