C program for area of a cylinder

Write a c program to find the volume and surface area of cylinder

C program for area of a cylinder

C code:

#include<stdio.h>

#include<math.h>

int main(){

    float r,h;

    float surface_area,volume;

    printf("Enter size of radius and height of a cylinder : ");

    scanf("%f%f",&r,&h);

    surface_area = 2 * M_PI * r * (r + h);

    volume = M_PI * r * r * h;

    printf("Surface area of cylinder is: %.3f",surface_area);

    printf("\nVolume of cylinder is : %.3f",volume);

    return 0;

}

Sample output:

Enter size of radius and height of a cylinder: 4 10

Surface area of cylinder is: 351.858

Volume of cylinder is: 502.655

 

Formula of surface area of cylinder:

Surface_area = 2 * Pie * r * (r + h)

Formula of volume of cylinder:

Volume = Pie * r * r * h

Pie = 22/7 or 3.1415926535....
