Kotlin | Surface area of Sphere: Here, we are going to implement a Kotlin program to find the surface area of Sphere.
Submitted by IncludeHelp, on May 22, 2020

Problem statement

Given the value of radius (r), we have to find the Surface area of Sphere.

Example:

Input:
radius = 12.6

Output:
surface area = 1995.036998735662

Kotlin - Find surface area of Sphere

Formula to find surface area of Sphere: = 4*PI*r^2

Program to find surface area of Sphere in Kotlin

package com.includehelp

import java.util.*
import kotlin.math.pow

//Main Function , Entry point of Program
fun main(args: Array<String>) {

    //Input Stream
    val scanner = Scanner(System.`in`)

    //Input Radius
    print("Enter Radius of Sphere : ")
    val radius = scanner.nextDouble()

    //surface Area of Sphere
    val sphereSurfaceArea = 4*Math.PI*radius.pow(2)

    //Print Surface Area
    println("Surface Area of Sphere on radius $radius is :$sphereSurfaceArea")
}

Output

Run 1:
Enter Radius of Sphere : 6
Surface Area of Sphere on radius 6.0 is :452.3893421169302
---
Run 2:
Enter Radius of Sphere : 12.6
Surface Area of Sphere on radius 12.6 is :1995.036998735662
