To find the radius of the circular region, we need to know its area. We can use the formula for the population density:

Population density = Population / Area

Rearranging the formula to solve for the area, we get:

Area = Population / Population density

Substituting the given values, we have:

Area = 360,000 / 1415 = 254.78 square miles

The formula for the area of a circle is:

Area = πr^2

Solving for the radius, we get:

r = √(Area / π)

Substituting the calculated area, we have:

r = √(254.78 / π) ≈ 9.02 miles

Therefore, the radius of the circular region is approximately 9.02 miles.
