tep $2.$ Figure out which points are in the circle

Let's add an if statement to the program so that points inside the circle are gray and points outside it are black.

First, delete the reference to drawPoint$($x$,$y$,$color$1)$;

Now copy the code below and change the "something" and "something else" to some formula that will detect if the random point $($x$,$y$)$ is within the circle:

if $($ something $<$ something else$)\{$

drawPoint$($x$,$y$,$color$2)$;

$\}$ else $\{$

drawPoint$($x$,$y$,$color$1)$;

$\}$

Advice #$1$: In the code use sqrt$()$ for $$

Advice #$2$: Use x$*$x instead of x$^2$ it's a long story why x$^2$ usually doesn't work.

Advice #$3$: To make things easier the code defines the center of the circle is at x $=0,$ y $=0.$ That makes the formula for the distance between the point $($x$,$y$)$ and the origin rather simple.

Advice #$4$: Use the diagram below for help:
