The area of a circle is given by: (pi)(r^2)\r
\n" ); document.write( "\n" ); document.write( "The given diameter is 10 inches.
\n" ); document.write( "The radius is half the diameter. r = 10/2 = 5 inches.\r
\n" ); document.write( "\n" ); document.write( "A = (3.14)(5^2)
\n" ); document.write( "A = (3.14)(25)
\n" ); document.write( "A = 78.5 square inches.
\n" ); document.write( "
\n" );
