Answer to Question #99400 in C++ for Caleb

Question

Given sphereRadius and piVal, compute the volume of a sphere and assign sphereVolume with the result. Use (4.0 / 3.0) to perform floating-point division, instead of (4 / 3) which performs integer division.

Volume of sphere = (4.0 / 3.0) π r3 (Hint: r3 can be computed using *)

Answer 1

#include<iostream>

using namespace std;

int main() {
	double sphereRadius;
	double piVal = 3.141592;

	cin >> sphereRadius;

	double r3 = sphereRadius * sphereRadius * sphereRadius;
	double sphereVolume = (4.0 / 3.0) * piVal * r3;

	cout << sphereVolume;

	return 0;
}
