Progarm to find curved and total surface area and volume of a cone in C

Program

#include <stdio.h>
int main()
{
    float r,h,l,tsa,csa,v;
    printf("**************************************************************");
    printf("\n**************************************************************");
    printf("\n** WAP to find curved & total surface area & volume of cone **");
