Question 399510
A square garden has an area of 1089 squared feet, and the gardener wants to
 install a sprinkler (with a circular 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?
:
The minimum radius would be half the diagonal of the garden, right?
:
Side of the garden = {{{sqrt(1089)}}}
Find the hypotenuse
h = {{{sqrt(2*sqrt(1089)^2)}}} = {{{sqrt(2(1089))}}} = {{{sqrt(2178)}}}
diagonal = 46.669
radius: 23.33 ft
