Question

about 50 percent of the population of Alaska lives within a 50 mile radius of Anchorage if the total area of Alaska is 580 6412 square miles about what percent of the total land area is within 50 miles of Anchorage

Answer 1

We divide the area of a 50-mile radius circle around Anchorage by the total area of Alaska.

The area of the circle is 50*50*pi=2500pi.  Dividing this by 5,806,412, we get .0013, or .13 percent.
