<h1>Using <code>blahtexml --xmlin</code></h1>
<p>In general, the distance of a point with coordinates <span class="ieq" b:inline="(x,y)"/> to the origin <span class="ieq" b:inline="(0,0)"/> is <span class="ieq" b:inline="\sqrt{x^2+y^2}"/>. A circle of radius <span class="ieq" b:inline="r"/> is the set of points that are at a distance <span class="ieq" b:inline="r"/> of its center. So, the equation of a circle of radius <span class="ieq" b:inline="r"/> centered at the origin is <span class="eq" b:block="x^2+y^2=r^2\text{.}"/></p>
