Program to accept the dimension and display surface area and volume of a cylinder

Write a program to accept the dimensions of a cylinder and display the surface area and volume of a cylinder:

Formula of the surface area of cylinder:-

surface_area=2*pie*r(r+h)

Formula of volume of cylinder:-

volume=pie*r*r*h

pie = 22/7

1. #include<stdio.h> 
2. #include<conio.h>
3. #define PI 3.1415
4. void main()
5.   {   
6.     float r,  h, surf_area, volume;  
7.     clrscr();
8.     printf(" Enter a size of Height and radius of a cylinder:");
9.     scanf("%f%f", &h, &r);
10.     surf_area = 2*PI*r*(r+h);  
11.     volume=PI*r*r*h;
12.     printf("\n Surface area of cylinder is : %.3f", surf_area);  
13.     print("\n volume of cylinder is:%.3", volume);
14.     getch();
15.    }  

 output:- 

            Enter a size of height and radius of a cylinder: 4 2

            Surface area of cylinder is : 75.407997

            Volume of cylinder is: 50.271999
