Write a complete program that asks the user to input the height and radius of a cone (both of type double) and calls two individual functions to calculate the total area of the cone and the volume of the cone. The main function then prints these values with appropriate messages.

The program in C++ is as follows:

#include <iostream>

#include <math.h>

using namespace std;

double area(double r, double h){

   double A = 3.14 * r * (r + sqrt(h*h + r*r));

   return A;}

double volume(double r, double h){

   double V = (1.0/3) * 3.14 * r*r * h;

   return V;}

int main(){

   double radius, height;

   cout<<"Radius: "; cin>>radius;

   cout<<"Height: "; cin>>height;

   cout<<"Area: "<<area(radius,height)<<endl;

   cout<<"Volume: "<<volume(radius,height);

   return 0;

}

Explanation:

This declares the area function

double area(double r, double h){

Calculate area

   double A = 3.14 * r * (r + sqrt(h*h + r*r));

Return the calculated area

   return A;}

This declares the volume method

double volume(double r, double h){

Calculate volume

   double V = (1.0/3) * 3.14 * r*r * h;

Return the calculated volume

   return V;}

The main begins here

int main(){

Declare radius and height

   double radius, height;

Get input for radius

   cout<<"Radius: "; cin>>radius;

Get input for height

   cout<<"Height: "; cin>>height;

Call the area function and print the returned value for area

   cout<<"Area: "<<area(radius,height)<<endl;

Call the volume function and print the returned value for volume

   cout<<"Volume: "<<volume(radius,height);

   return 0;

}

storage maybe?

are there options?
