A square lawn has area 338ft^2. A sprinkler placed at the center of the lawn sprays water in a circular pattern that just covers the lawn. What is the radius of the circle?
\n" ); document.write( "

If it sprays in a circular motion, usually it will cover the circle that's INSCRIBED in the square. As such, the diameter will be the same length as one of the sides of the square, 
\n" );
document.write( "and the radius will be  the diameter, or .
\n" );
document.write( "However, if it sprays in a circular motion, and covers the entire square lawn, then a situation is created wherein it's covering more than the entire square, which is
\n" );
document.write( "INSCRIBED within the CIRCLE. As such, the diameter will be the length of the DIAGONAL of the square, which you would then find, and  of that value will be your radius!.
\n" );
document.write( "Therefore, it's NEVER going to JUST cover the lawn. It's either it will cover part of the lawn, or more than the lawn. You determine which it is! \n" );
