Question

Write a C++ program that reads in the radius of a Sphere, then calculates and prints its volume and surface area. 

Answer 1

#include <iostream>
using namespace std;
 
const float pi = 3.1415;

 float volume(float r) {
    return (float(4) / float(3)) * pi * r * r * r;
 }
 
float surface_area(float r) {
    return  4 * pi * r * r;
}
 
int main() {
    float radius;
    float vol, surfaceArea;
      
   cout<<"Enter radius: ";
   cin>>radius;
   
    vol = volume(radius);
    surfaceArea = surface_area(radius);
 
    cout << "Volume:  " << vol << endl;
    cout << "Surface: " << surfaceArea << endl;
    return 0;
}
