C program for Calculation of the surface and the volume of a cone

C program for Calculation of the surface and the volume of a cone

#include<stdio.h>
#include<conio.h>
#include<math.h>
void main()
{
 float r,h;
 float sa,volume;
 clrscr();

 printf("Enter length of radius and height of cone:\n");
 scanf("%f\n%f",&r,&h);
 
 sa=3.141*r*(r+sqrt(r*r+h*h));
 volume=(1.0/3)*3.141* r * r * h;
 printf("Surface area of cone is: %.3f",sa);
 printf("\nVolume of cone is : %.3f",volume);

 getch();
}

OUTPUT:

Enter size of radius and height of a cone: 3 10
Surface area of cone is: 126.672
Volume of cone is: 94.248
