如何从Google Maps V3中删除圈子？

Question

我画了一个圆圈

    circle = new google.maps.Circle({
    map: map,
    radius: r,    // 1 miles in metres = 1609.3 m
        strokeWeight:1,
        strokeOpacity:0.5,
        fillOpacity:0.2,
        fillColor: '#AA0000'
    });
    circle.bindTo('center', marker, 'position');

如何从地图上删除圆圈？
