Find the Diameter or Longest chord of a Circle in C++
Suppose we have radius r is given. We have to find the diameter or longest chord of the circle. If the radius is 9, and diameter will be 18. This task is extremely simple, we have to find the 2*r, that is the diameter of the circle.
Example
#include<iostream>
using namespace std;
int getDiameter(int r) {
return 2*r;
}
int main() {
int r = 9;
cout << "The longest chord or diameter is : " << getDiameter(r);
}Output
The longest chord or diameter is : 18
