A zookeeper surveyed 72 animals to determine their primary diet. It was found that 18 animals are carnivores, 12 are herbivores, and 6 are omnivores. Of the remaining animals, one-quarter are piscivores (fish-eaters), one-quarter are insectivores (insect-eaters), and the rest are frugivores (fruit-eaters). If a pie chart is created to represent this data, what is the measure in degrees of the central angle for the sector representing frugivores?
