About 370,000 people live in a circular region with a 5000000 radius. find the population density in people per square mile

By definition, the area of a circle is given by:

Where,

r: radius of the circle

Then, the density of the population is given by:

Where,

n: number of people

Substituting values we have:

Rewriting:

the population density in people per square mile is:

6,250

step-by-step explanation:

to get the area, multiply 360 by 160.(57,600)

to find out how many bags of fertilizer it will take, first figure out how many square feet one bag can hold. divide 1000 by 8(125) to get the unit rate(how many square feet one pound of fertilizer can hold)and multiply it by 50(6250). if i haven't made a mistake, that is the answer.
