A sprinkler that sprays water in a circular motion is to be used to water a square garden. If the area of the garden is 920 square feet, find the smallest whole number radius that the sprinkler can be adjusted to so that the entire garden is watered.
--------------
Each side of the garden is sqrt(920) ft..
----
The diagonal of the garden is sqrt(920)*sqrt(2) = 42.895 ft
----
Required radius = 42.895/2 = 21.45 ft
