Answer:
The area of the country is 17 square miles
Step-by-step explanation:
To calculate the population density of the country. We employ the use of a mathematical formula. This can easily be obtained from the units of the density
The population density = Population of the country/area of the country
Since we are to calculate the area of the country, the equation becomes
Area of country = Population of country/population density of country
Area of country = 4288/257
Area of country = 16.68 square mile
To the nearest square mile, the Area of the country = 17 square mile
14 degrees. It equals half the intercepted arc.
