A micrometer reading is made at dimension D on a tapered shaft (Figure 217). For each of the problems use the dimensions given in the table, compute the taper, set up a proportion, and determine diameter C to 3 decimal places.
According to the AVMA website, the number of dogs in the US in 2010 was 73 million, the number of horses was 7 million and the number of cats was 86 million. We draw a circle to represent the number of dogs that has a radius 9 cm. We want to make a circle to represent the number of horses. The area of the dog circle and the area of the horse circle should be the same ratio as the populations. What should be the radius of the horse circle? Report your answer to the nearest tenth of a centimeter (cm). cm
