    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.
