Find the area of a square inscribed in a circle inscribed in an equilateral triangle. The radius of a circle inscribed in an equilateral triangle is a/(2√3).
The diameter of the circle is the diagonal of the square, d = 2 * r = a/ √3
The formula for the area of the square is ½ d2,
A = 0.5 * d2 A = (1/2) * (a2) / (3) = (a2/6)
#include <iostream> using namespace std; int main() { float area,a = 10; area = (a*a) / 6; cout <<"area = "<<area<< endl; return 0; }
area = 16.6667
