kotlin 查找id

A cylinder is a three-dimensional structure which has circular bases parallel to each other.

圓柱是具有彼此平行的圓形底的三維結(jié)構(gòu)。

Formula to find area of a cylinder: 2*PI*(radius+height)

查找圓柱體面積的公式：2 * PI *(半徑+高度)

Give radius and height, we have to find area of a cylinder.

給定半徑和高度，我們必須找到圓柱體的面積。

Example:

例：

Input:Radius = 5Height = 7Output:Surface Area of Cylinder is :75.39822368615503

查找Kotlin圓柱體面積的程序 (Program to find area of a cylinder in Kotlin)

package com.includehelpimport java.util.*//Main Function , Entry point of Program fun main(args: Array<String>) {//Input Streamval scanner = Scanner(System.`in`)//Input Radiusprint("Enter Radius of Cylinder : ")val radius = scanner.nextDouble()//Input Heightprint("Enter Height of Cylinder : ")val height = scanner.nextDouble()//Cylinder Surface Areaval areaCylinder = 2*Math.PI*(radius+height)//Print Areaprintln("Surface Area of Cylinder is :$areaCylinder") }
