\n" ); document.write( "I assume by \"wide\" you mean the diameter.
\n" ); document.write( "The area of the whole circle is \"pi%2Ar%5E2\"
\n" ); document.write( "r = d/2 = 1.5 feet
\n" ); document.write( "Area = 2.25*pi
\n" ); document.write( "Area/2 = 1.125*pi square feet
\n" ); document.write( "Area/2 =~ 3.534 sq feet
\n" ); document.write( "
\n" ); document.write( "
