英语翻译
As in Fig ,the radius(半径)of every little circle is 1cm ,then the area of non-shadowy part(未涂色)is ________c㎡(请写出具体过程,

你这个图是不是6个小圆与大圆围着一圈相切,然后中间一个小圆与其他六个小圆相切,未涂色部分是除了小圆外的部分.
如果是这样的话,大圆半径就是3cm(一条直线上的三个小圆圆心相连延长就是直径,∴大圆直径=3×小圆直径).
∴未涂色的面积=大圆面积-7个小圆面积=π×3²-7×π×1²=2π≈6.28(cm²)

没图回答不了啊

如图,每一个小圆的半径都是1厘米,那么未涂色部分的面积等于多少平方厘米?
没有图!有一个图,是在一个大圆里面有7个小圆,7个小圆涂成了黒色。不好意思,我不会把画图。我没看到图,不知道小圆的位置怎么排的,所以无法计算大圆的半径,也就无法计算面积了 你可以在小画家里画圆...

如图,为每一个小圆的半径是1厘米,然后未涂色部分的面积多少平方厘米。没有图片啊。算不来。
