Question

In a search-and-rescue mission, a team maps out a circular search area from the last known location of a group of hikers. If the search region is 113.04 mi^2, how far from the last known location, to the nearest mile, is the team searching? Use pi=3.14

Answer 1

area = 113.04 = pi*r^2
113.04 = 3.14 * r^2
r^2=113.04/3.14
r=sqrt(113.04/3.14)
r=sqrt(36)
r=6

So the search radius is 6 miles around the last known location of the hikers

Answer 2

nice!! thnaks
