Two people are comparing their weights, but their heights are quite different; one is 5 feet tall, and the other is 6 feet tall. They might consider their bodies as roughly cylindrical. The smaller person notes that his waistline is 30 inches, meaning the diameter of his cylinder might be about 10 inches. If the taller person were proportionally built, his diameter would be 12 inches, and the smaller person's cylinder has a volume of about 4,700 in3. What is the approximate cylinder volume of the taller person? Round your answer to the nearest whole number.
