a sprinkler that sprays water in a circular motion is to be used to water a square garden.
\n" ); document.write( " If the area of the garden is 920 square feet, find the smallest whole number
\n" ); document.write( " radius that the sprinkler can be adjusted to so that the entire garden is watered.
\n" ); document.write( ":
\n" ); document.write( "The diagonal (d) of the square will = the diameter of the required circle
\n" ); document.write( ":
\n" ); document.write( "Let x = side of the square
\n" ); document.write( "x^2 = 920 sq/ft, the area of the square
\n" ); document.write( "and using pythag
\n" ); document.write( "d = \"sqrt%28x%5E2+%2B+x%5E2%29\"
\n" ); document.write( "Which is
\n" ); document.write( "d = \"sqrt%28920%2B920%29\"
\n" ); document.write( "d = \"sqrt%281840%29\"
\n" ); document.write( "d = 42.895
\n" ); document.write( "radius = \"42.895%2F2\"
\n" ); document.write( "r = 21.4476 ~ 22 ft smallest whole number radius to water the entire garden \n" ); document.write( "
\n" );
