推荐答案

您不能改变在谷歌地图圆圈的大小，原因很简单，它的大小是很重要的。

You cannot change the size of the circle in Google Maps, for the simple reason that its size is very important.

蓝色圆圈涵盖在其中已放置的区域。定位技术并不precise，和圆是说，我们知道你在什么地方，但不知道确切位置在那里。

The blue circle covers the area in which you have been placed. Location technologies are not precise, and the circle is to say that "We know you're somewhere in here, but not sure exactly where in there".

如果你被允许改变圆的大小，它会破坏圆的目的。

If you were allowed to change the size of the circle, it would defeat the purpose of the circle.
