Area of Circumcircle of a Right Angled Triangle in C Program?

Here we will see how to get the area of circumcircle of a right angled triangle. The hypotenuse of the triangle is forming the diameter of the circle. So if the hypotenuse is h, then radius is h/2

So the area is −

Example Code

#include <iostream>
#include <cmath>
using namespace std;
float area(float h) {
   if (h < 0) //if h is negative it is invalid
      return -1;
   float area = 3.1415 * (h/2) * (h/2);
   return area;
int main() {
   float h = 8;
   cout << "Area : " << area(h);


Area : 50.264
