About 650,000 people live in a circular region with a 6-mile radius. The population density in people per square mile: 650000/(36 pi) = 5747.261833874

area = 36π mi² density = 650,000 people/(36π mi²)

650,000/(36π)

Ans. 650000/[(pi)6^2]=5747 p/mile^2 approximately.

Area = pi (6)^2 = 36pi 650,000 / (36pi) = 5747.26 Approximately 5747 people per square mile

the population density = population / area

650,000/(36π ≈ 5747 people/mile^2

650,000/(36*pi) = about 5700 but use a calculator.
