A rectangular lawn has an area of 126 square meters. Surrounding the entire lawn is a flower border that is 4 meters wide. The area of the flower border alone (not including the lawn) is 264 square meters. A sprinkler is installed in the middle of the lawn that sprays water in a circle. Rounded to the nearest 10th of a meter, what is the minimum spraying radius necessary in order for the sprinkler to water both the lawn AND the entire flower border?
