# Program to find area of a Circular Segment in C++

In this tutorial, we will be discussing a program to find area of a circular segment.

Making a chord in a given sphere divides it into two segments - major and minor. Given the radius of the circle and angle making the minor segment, we are required to find the areas of both segments.

## Example

#include <bits/stdc++.h> using namespace std; float pi = 3.14159; //finding area of segment float area_of_segment(float radius, float angle){ float area_of_sector = pi * (radius * radius)*(angle / 360); float area_of_triangle = (float)1 / 2 *(radius * radius) * sin((angle * pi) / 180); return area_of_sector - area_of_triangle; } int main() { float radius = 10.0, angle = 90.0; cout << "Area of minor segment = " << area_of_segment(radius, angle) << endl; cout << "Area of major segment = " << area_of_segment(radius, (360 - angle)); return 0; }

## Output

Area of minor segment = 28.5397 Area of major segment = 285.619
