Write a complete program that prompts the user for the radius of a sphere, and calculates and prints the volume of that sphere.

Question

Use an inline function sphereVolume that returns the result of the following expression:
```
(4.0 / 3.0 * 3.14159 * pow(radius, 3)).
```

Answer 1

```
// Exercise 6.10 Solution: ex06_10.cpp
// Inline function that calculates the volume of a sphere.
#include
#include
using namespace std;

const double PI{3.14159}; // define global constant PI

// calculates volume of a sphere
inline double sphereVolume(const double radius) {
return 4.0 / 3.0 * PI * pow(radius, 3);
}

int main() {
// prompt user for radius
cout << "Enter the length of the radius of your sphere: ";
double radiusValue;
cin >> radiusValue; // input radius

// use radiusValue to calculate volume of sphere and display result
cout << "Volume of sphere with radius " << radiusValue
<< " is " << sphereVolume(radiusValue) << endl;
}
