what is the solution of if the perimeter of a semicircle is 72cm
\n" ); document.write( "Find the radius of the semi-circle
\n" ); document.write( "diameter + half the circumference = 72 cm
\n" ); document.write( "2r + pi*r = 72
\n" ); document.write( "r(2+pi) = 72
\n" ); document.write( "r = \"72%2F%28%282%2Bpi%29%29\"
\n" ); document.write( "r = 14
\n" ); document.write( ":
\n" ); document.write( "what will be the area of that semicircle?
\n" ); document.write( "A =\"1%2F2\"*\"pi%2A14%5E2\"
\n" ); document.write( "A = 307.9 sq/cm
\n" ); document.write( "
\n" ); document.write( "
\n" );
