The Greek letter for the circle constant, 3.14159…

In HTML, CSS and JavaScript

<p>&pi;</p>           <!-- or the character itself in a UTF-8 page -->

.note::before { content: "\03C0"; }

const s = "\u03C0";

In a page saved as UTF-8 (the default today) you can paste the character directly; the entity is only needed when it must survive a non-UTF-8 system. Encode or decode whole texts with the HTML Entity Encoder.
