You can put this solution on YOUR website!
she has specifically asked you to multiply by pi
\n" ); document.write( "pi on the calculator has a value of 3.14159265\r
\n" ); document.write( "\n" ); document.write( "169*3.14=530.66
\n" ); document.write( "BUT
\n" ); document.write( "169*pi=530.929 (round off to 100 th.
\n" ); document.write( "530.93
