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

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
