kotlin 查找id

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

圆柱是具有彼此平行的圆形底的三维结构。

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

查找圆柱体面积的公式：2 * PI *(半径+高度)

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

给定半径和高度，我们必须找到圆柱体的面积。

Example:

例：

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

查找Kotlin圆柱体面积的程序 (Program to find area of a cylinder in Kotlin)

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