Question

Please hurry this is very urgent!!!!About fifty percent of the population of Alaska lives within a 50-miles radius of Anchorage. Of the area of Alaska is 586,412 miles, about what percent of the total land area is within 50 miles of Anchorage?

Answer 1

Answer: About 1.34%.

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 :_

`(7850)/(586412)*100=1.3386492773\approx1.34\%`

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