Vertically align text inside of the svg circle

I am trying to centre the <text> inside of the <path> element. Path is a circle drawn using @opsb great answer. I can centre the text horizontally using text-anchor='middle'.

Is there a way to centre it Vertically?

<svg width="200px" height="200px" version="1.1" xmlns="http://www.w3.org/2000/svg">
  <path id='path' fill="transparent" stroke='red' stroke-width='6'/>
  <text x="100" y="100" font-family="Verdana" font-size="50" fill="blue" text-anchor='middle'>5</text>
</svg>

JSFiddle with the javascript.

Svg center text

Since svg is responsive I usually put in a hard value that is about the radius of the circle.

So simply by adding: transform="translate(0, 15)

function polarToCartesian(centerX, centerY, radius, angleInDegrees) {
  var angleInRadians = (angleInDegrees - 90) * Math.PI / 180.0;

  return {
    x: centerX + (radius * Math.cos(angleInRadians)),
    y: centerY + (radius * Math.sin(angleInRadians))
  };
}

function describeArc(x, y, radius, startAngle, endAngle) {

  var start = polarToCartesian(x, y, radius, endAngle);
  var end = polarToCartesian(x, y, radius, startAngle);

  var arcSweep = endAngle - startAngle <= 180 ? "0" : "1";

  var d = [
    "M", start.x, start.y,
    "A", radius, radius, 0, arcSweep, 0, end.x, end.y
  ].join(" ");

  return d;
}

$('#path').attr("d", describeArc(100, 100, 50, 0, 180));
