A city's limits form a perfect circle that has a diameter of 24 kilometers. The city has a population density of 470 people per square kilometer. What is the city's population? Round to the nearest integer. Your answer Report issue 106.877 people X Correct answer 212623 people Explanation The population density is equal to the total number of people divided by the area. P D = A First find the land area of the city. Recall that the area of a circle with radius r is given by A = r. This circular city has diameter of 24 kilometers, so its radius is 12 kilometers. A=122452.3893421 The land area of the city is about 452.3893421 square kilometers. Now use the land area and the density to find the population.
