About 150,000 people live in a 8-mile radius of a city's town hall. Find the population density in people per square mile. Round

S_A_V [24]

Answer:

747 people per square mile

Step-by-step explanation:

population of city's town hall = 150,000

Radius of city's town hall = 8 mile

area of any circular shape is given by $\pi r^2$ .

r is the radius of circle.

Area of city's town hall = $\pi r^2= 3.12*8^2 = 3.14*64 = 200.96$

Population density for any place is ratio of population of that place to area of that place

Thus

Population density for city's town hall = population of city's town hall /Area of city's town hall

Population density for city's town hall = 150,000/200.96

Population density for city's town hall= 746.42 people per square mile.

Population density for city's town hall Rounded to the nearest whole number is 747 people per square mile.
