Question 635952: A square garden has an area of 1024 squared feet, and the gardener wants to install a sprinkler (with a circluar spraying pattern) at the center of the garden. What is the minimum radius of spray the sprinkler would need in order to water all of the garden?

Area = 1024
side^2=1024
side = sqrt(1024)
side = 32
Find the diagonal
Half the doagonal is the radius to cover the entire square garden
32^2+32^2= diagonal ^2 ( Pythagoras theorem)
2048 = diagonal ^2
diagonal = 45.25
Radius = 45.25/2
radius = 22.625 feet
