Answer:
Approximately 883,572 people
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.
