**Formula of surface area of cone:**

Surface_area = Pie * r * (r + √ (r

^{2}+ h^{2}))**Formula of volume of cone:**

Volume = 1/3 * Pie * r

^{2 }* 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
