How to remove circle from Google Maps V3?

问题

I have drawn circle using

    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');
