Could you please tell me where is the error in the code? dw keeps showing the second and third errors.

<?php

echo' 3 ways to write pi: <p>';

echo'The first way: pi()='.pi ().'<p>';

echo'The second type: 3.14159265359='.3.14159265359.'';

echo'The third type: 314159265359E-11='.314159265359E -11.'<p>';
