A region with a 15-mile diameter has a population density of about 5000 people

per square mile. Find the number of people who live in the region.

Approximately 883,572 people

Step-by-step explanation:

I'm assuming the region is a circle.

The formula for finding the area of a circle is A=πr².

Since we know that the diameter of the region is 15 miles, and a diameter is 2 times the radius, the radius must be 7.5 miles. We also know that π is equal to 3.14159265359.

A=πr²

A = 3.14159265359*7.5²

A = 3.14159265359*56.25

A = 176.714586764

The region has an area of 176.714586764 square miles.

176.714586764*5000=883572.933822

We can round this number to the nearest whole, but since we cannot have part of a person, the answer is approximately 883,572 people.
