Find the circumference of a circle with radius 5 cm. 相关知识点: 试题来源: 解析 10π cm 首先,题目要求计算半径为5 cm的圆的周长。 已知圆的周长公式为:**C = 2πr**(其中r为半径)。 代入半径值r = 5 cm: **C = 2 ×π× 5 = 10π cm**。 单位与原题一致(厘米),计算过程无误。
(1)定义一个Circle类,包含一个double型的radius属性代表圆的半径,一个findArea()方法返回圆的面积。 (2)定义一个类PassObject,在类中定义一个方法printAreas(),该方法的定义如下:publicvoidprintAreas(Cirlce c,inttimes) 在printAreas方法中打印输出1到time之间的每个整数半径值,以及对应的面积。例如,times为5,...

If you want to find the area of a circle with a radius of 5, what formula should you use? A. A = πr² B. A = 2πr C. A = πd D. A = r² 相关知识点: 试题来源: 解析 A。解析:求圆的面积公式是 A = πr²,B 选项是圆的周长公式;C 选项是圆的周长公式中直径表示...
To find the area of a circle, you take pi times the radius squared, or A = pi r^2. Using this formula, you can find the area of a circle if you know the radius -- or the diameter -- by plugging in your values and solving for A. Pi is approximated as 3.

Because all circles have the same shape, their different measurements are related by a set of simple equations. If you know the radius, diameter, area or circumference of a circle, it is fairly easy to find any of the other measurements.
