You can put this solution on YOUR website!
Remember that Area = pi * rad^2
\n" ); document.write( ".
\n" ); document.write( "we are given diameter = 42, or radius = 21 ,,,,(42/2)
\n" ); document.write( ".
\n" ); document.write( "Area = pi * r^2 = pi * 21^2 = pi * 441 = 1385.44 inches ^2\r
\n" ); document.write( "\n" ); document.write( ".\r
\n" ); document.write( "\n" ); document.write( ".\r
\n" ); document.write( "\n" ); document.write( "an obscure Area formula is A = pi d^2 /4 = pi 42^2 /4 = 1385.44 also
\n" ); document.write( ".
