JavaScript的多個值的圓周，直徑和半徑

Question

我正在嘗試創建一個JavaScript程序，它將提示用戶輸入一個數字範圍「3-6」，然後輸出每個數字的面積，半徑和周長在範圍中。

下面是我的代碼到目前爲止，我知道它目前不工作，但幾個指針會很棒！

function circum() { 
var radius = prompt("Enter the a range of numbers for the circle",""); 
var radiusanswer = 2 * Math.PI * radius; 
var area = radius * radius * Math.PI; 
var cube = radius * radius * radius 
alert("The circumference is "+radiusanswer) 
alert("The area is "+area) 
alert("The cube is "+cube) 

Answer 1

你就近了。只是需要循環正確有效範圍內的所有號碼，如下面的感謝

function circum() { 
 
    var values = prompt("Enter the a range of numbers for the circle", ""); 
 
    var range = values.split("-"); 
 
    //range[0] = start value 
 
    //range[1] = end value 
 
    for (var i = range[0]; i <= range[1]; i++) { 
 
    var radius = i; 
 

 
    var radiusanswer = 2 * Math.PI * radius; 
 
    var area = radius * radius * Math.PI; 
 
    var cube = radius * radius * radius 
 
    console.log("The circumference is " + radiusanswer) 
 
    console.log("The area is " + area) 
 
    console.log("The cube is " + cube) 
 
    } 
 

 
} 
 
circum();
