How to display google map based on radius selected

I have a miles dropdown. When I select any value like 10 miles from dropdown my google map should display within 10-mile range of the place. How Do I do this?

<script src="https://maps.googleapis.com/maps/api/js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
      function myMap() {
            var myCenter = new google.maps.LatLng(56.1304, -106.3468);
            var mapProp = { center: myCenter, zoom: 6, scrollwheel: true, draggable: true, mapTypeId: google.maps.MapTypeId.ROADMAP };
            var map = new google.maps.Map(document.getElementById("googleMap"), mapProp);

            marker.setMap(map);
        }

<div id="googleMap" style="height: 100%; width: 100%; position: absolute; top: 0px; left: 0px; "></div>
<div id="searchcontainer" style="position: absolute; z-index: 0; left: 450px; top: 0px;">
    <select id="range" name="range">
        <option value="0">Current Map</option>
        <option value="5">5 Miles</option>
        <option value="10">10 Miles</option>
        <option value="15">15 Miles</option>
        <option value="20">20 Miles</option>
        <option value="25">25 Miles</option>
        <option value="50">50 Miles</option>
        <option value="100">100 Miles</option>
        <option value="250">250 Miles</option>
        <option value="500">500 Miles</option>
    </select>

</div>

You don't require center in your map. what you can possibly do is to add a listener and upon changing setZoom accordingly but you need to change your range values not text according to Google Maps API documentation to handle max zoom values.

var range = document.getElementById("range");
      range.addEventListener("change", function() {
        map.setZoom(range.value);
      });

One option is to create a google.maps.Circle with the correct center and desired radius, then call map.fitBounds(circle.getBounds()) (where circle is the circle).

(note that radius of the circle is in meters, so you will need to convert your input of miles to meters).

screenshot of resulting map

var METERS_PER_MILE = 1609.34;

function myMap() {
  var myCenter = new google.maps.LatLng(56.1304, -106.3468);
  var mapProp = {
    center: myCenter,
    zoom: 6,
    scrollwheel: true,
    draggable: true,
    mapTypeId: google.maps.MapTypeId.ROADMAP
  };
  var map = new google.maps.Map(document.getElementById("googleMap"), mapProp);
  var circle;
  google.maps.event.addDomListener(document.getElementById('range'), 'change', function(evt) {
    var value = $("#range").val();
    if (circle && circle.setMap) circle.setMap(null);
    circle = new google.maps.Circle({
      center: myCenter,
      radius: value * METERS_PER_MILE,
      map: map
    });
    map.fitBounds(circle.getBounds());
  });
}
google.maps.event.addDomListener(window, 'load', myMap);
