You can put this solution on YOUR website!
surface area of cone = pir(r+s) where r is the radius and s the slant height\r
\n" ); document.write( "\n" ); document.write( "radius =17 inch\r
\n" ); document.write( "\n" ); document.write( "slant height = 20 inch\r
\n" ); document.write( "\n" ); document.write( "3.14*17*(17+20)
\n" ); document.write( "= 1976.06 sq. in
\n" ); document.write( "
\n" );
