About 1.75 million people live in a circular region with a 15-mile diameter. find the population density in people per square mile. round your answer to the nearest whole number.

The diameter of the circular region is 15 miles

that gives radius = 7.5 miles

Now,

Area = π r² = 3.14 * 7.5* 7.5

= 176.625 mile²

Population density = number of people / land area

this is =  

Now rounding off to nearest whole number, we get 9908

So, there  are 9908 population living in per square mile.
