Question

Calculate and print the area and volume of a cone inside a While  loop that goes from 1 to 20 with a step of .5. (the step is 1/2 or Point 5, so you go 10, 10.5,11, 11.5)

Note: Your loop variable will need to be a double data type

Use two decimal places on all numbers that are double data type.

This will be a table with 3 columns.

Use r as the loop counter and as the radius. Let the height of the cone be twice the radius.

Below the while loop, print the sum of all 3 columns.

In C++, please use visual studios and post the output

Answer 1

#include <iostream>
using namespace std;

#define PI 3.14159

int main() {
    cout << "Radius\tHeight\tVolume" << endl;
    double r = 1, h, v, rTotal = 0, hTotal = 0, vTotal = 0;
    while (r <= 20) {
        h = 2*r;
        v = PI * r *r * h/3;
        rTotal += r;
        vTotal += v;
        hTotal += h;
        cout << r << "\t\t" << h << "\t\t" << v << endl;
        r += 0.5;
    }
    cout << rTotal << "\t\t" << hTotal << "\t\t" << vTotal << endl;
    return 0;
}
