Answer:
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;
}
