Write a program to find the area of sphere

#include<stdio.h>

#include<conio.h>

int main()

{

    float r,v,area;

    printf("Enter the radius of the sphere\n ");

    scanf("%f",&r);

    area=4*3.14*r*r*r;

    v=(4/3.14)*3.14*r*r*r;

    printf("volume of the sphere=%f\n", v);

    printf("area of sphere=%f\n",area);

    getch();

    

    }
