write a c program to find the volume and surface area of cone | CTechnotips

Formula of surface area of cone:

Surface_area = Pie * r * (r + √ (r² + h²))

Formula of volume of cone:

Volume = 1/3 * Pie * r² * h

Pie = 22/7 or 3.14159265358979323846264338327950288419716939937510...

Write a c program or code to find or calculate the volume and surface area of cone

#include<stdio.h>

#include<math.h>

int main(){

    float r,h;

    float surface_area,volume;

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

    scanf("%f%f",&r,&h);

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

    volume = (1.0/3) * M_PI * r * r * h;

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

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

    return 0;

}

Sample 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
