C Program - Accept dimensions of cylinder and print the surface area and volume

Program

#include <stdio.h>
#include <math.h>
int main()
{
    float radius, height;
    float surface_area, volume;
    printf("Enter  value for  radius and height of a cylinder : \n");
    scanf("%f%f", &radius, &height);
    surface_area = 2 * (22 / 7) * radius * (radius + height);
    volume = (22 / 7) * radius * radius * height;
    printf("Surface area of cylinder is: %f", surface_area);
    printf("\n Volume of cylinder is : %f", volume);
}

Output:
Enter  value for  radius and height of a cylinder :
4
6
Surface area of cylinder is: 240.000000
 Volume of cylinder is : 288.000000
