我是在试着，去解圆的半径。

I am trying to solve, actually, for the radius of the circle.

我们正在测量圆的半径。

We are measuring the radius of the circle.

youdao

这个圆的半径有多长？

What is the radius of this circle?

youdao

一个圆的半径是4厘米，它的面积是多少平方厘米？

The radius of a circle is 4cm, how many square centimeters is its area?

youdao

就是C所包围的区域。，Well，，R，is，the，region，enclosed，by，C。,如果C是一个圆，R就是半径为a的圆盘。

R So if C is the circle, R is the disk of radius A.

youdao

接着，创建一个spl函数，它将返回给定半径的圆的面积。

Next, create an SPL function that returns the area of a circle given its radius.

youdao

是一个半径为1的圆，那是单位圆。

That is a circle of radius 1. That's the unit circle.

youdao

我们能用半径计算出圆的面积。

The full moon has a circular form.

拖动此形状，可添加一个由半径定义的圆。

Drag to add a circle defined by radius.
