Answer 2

Answer: About 1.34%.

Step-by-step explanation:

Given : About 50% of the population of Alaska lives within a 50-miles radius of Anchorage.

To find the area of the section within 50 miles , we need to find the area of the circle with radius =  50 miles.

Area of circle = $\pi r^2$

Then,

Area of the section within 50 miles= $(3.14) (50)^2=7850\text{ miles}^2$

Also, the area of Alaska is 586,412 miles.

Now, the percent of the total land area is within 50 miles of Anchorage :_

$\dfrac{7850}{586412}\times100=1.3386492773\approx1.34\%$

Hence, the percent of the total land area is within 50 miles of Anchorage= 1.34%
