Explanation:
Give me some time to think about this please.
When World War I broke out in Europe, the president Woodrow Wilson follow the policy stated in option B. He declared U.S. Neutrality and the right to trade with both sides.
Keeping in mind that, 1 in every 7 Americans were born in some of the countries at war, the president highly believed that his country must remain neutral. Besides that, by the time the WWI began The United States was in an economic recession, so his government couldn't provide any economic support to the war, and instead decided to focus on selling its goods to France and Britain because they were really interested in American products, and that's why the administration disguised neutral duties in ways that tended to favor the Allies.
A = pi * r^2 A = 3.14 * 50^2 A = 7,850 square miles (area of the 50 mile broadcast signal)
A = pi * r^2A = 3.14 * 75^2A = 17,662.5 = 17,663 square miles (area of the 75 mile relayed signal)
Now we just need to subtract the 50 mile signal from the 75 mile signal, so:
17,663 - 7,850 = 9,813 square miles greater
Hope this helps :)
